Help!

Received my empeg today. Everything was going great, until it stopped working properly! Whenever I try to sync now, it does weird things... reboots, doesn't recognize emplode, etc. Help!

Can anyone that thinks they can help either give me their number or call me?

My number is 415-647-6006, but I'll be happy to call you... just send me your number... jonbauer@pacbell.net

Been emailing Rob, but think he's prolly busy/working/sleeping...

- Thanx

Whenever I try to sync now, it does weird things...

Can you describe what's happening?
First thing that comes to mind is that you might be another victim of the loose cable saga.
Have you been through the "General/Help Please?" area on this BBS where this has been discussed?

If you have a chance, monitor the boot-up sequence and compare this with this post

On the phone with Tony now and he's trying to help

It seems to be finding your disks OK
You're lucky with Tony around the corner. I bet that reloading software is going to be the next step.
Good luck / Bon courage

mk2 6 nr 6

He's trying to reload the software now, it's locked at the part where it's trying to pump the hard disk. My read is that it's the same old hard disk connector problem, just that it's loose instead of completely undone...

He's going to try to get a hold of Rob now.

it's locked at the part where it's trying to pump the hard disk.

I've had pumping problems a few times when upgrading software.
In all of these cases the process got stuck with the 'repump partition' message when changing the player's software without resetting the player, when asked for (just letting it run). Abiding by the instructions / restarting the player when instructed allowed the pumping to progress as intended.

The Mk2 or the latest software seem more critical than when I still had the Mk1 . . .

Good luck

Maybe you have a bad ram chip on the board?

Sean

Maybe you have a bad ram chip on the board?

That was my first thought as well. However, note that the first memory access violation occurs in the player software- which is loaded from the hard disk. So it could be either.

In all of these cases the process got stuck with the 'repump partition' message when changing the player's software without resetting the player, when asked for (just letting it run).

I was on the phone with him at the time, and he did perform the upgrade by rebooting the player when it prompted him to. In fact, the upgrade wouldn't work at all unless he did it since the player was locked up.

Rob will deal with this directly, but we've had one mk2 with a bad ram chip; the RAM is a different brand to the stuff in the Mk1, but this shouldn't be a problem.

To perform a ram test, wait until the unit falls over (the other unit had a heat-related fault in the chip) then power cycle it and press Ctrl-T at the bootup prompt - it then goes through a basic hardware test. Do this a few times and note any errors.

Hugo

Well. My empeg is definitely hosed. I think it is heat related.

I tried to get the hardware test working, but no dice. Control-T has no effect during boot...

Looking forward to speaking with someone from empeg soon.

To perform a ram test, wait until the unit falls over (the other unit had a heat-related fault in the chip) then power cycle it and press Ctrl-T at the bootup prompt - it then goes through a basic hardware test.

Neat feature. Is that Mark2 only? I couldn't get my Mark1 to do anything with Ctrl-T.

By the way, Jon's problem could very likely be the RAM thing. His unit worked fine for a while (enough to upload a few albums), and it only went wonky on him after it had been powered up for a few hours. So if it was heat-related, that would make sense.

Also, it's not loose cables on his unit. Since the upgrade attempts were failing on the partition pump, it sure sounded like a disk problem. But Rob had just gone home for the night (it was about 9 or 10 o'clock UK time), and Jon wanted to know for sure if it was just a loose cable.

So he asked me to talk him through the lid removal, which I did. I hope you guys don't mind- I was confident that he knew what he was doing (and he did, he was very careful with it). I figured that even if the cables were fine, you would have at least wanted him to rule that out before going to the trouble of shipping it back. And I hated to see a new owner so distressed over his new toy malfunctioning.

He looked inside and noted that the hard disk cables were both properly connected (he has a dual-disk unit). So it's not the cables. He didn't remove the disk cradle at all, he just opened the lid and looked at the connectors.

After putting the lid and the face back on, he was able to install the 1.0 upgrade flawlessly and was able to use Emplode just fine again (as he had been able to do when he first got the unit). So I'm guessing it'll run for another couple of hours before going south on him again.

Too bad about the RAM chips...

Jon, I think that's enough logs for now. Rob will likely be in touch with you tomorrow (and possibly me too, so he can cut me a new orifice for telling you how to open the player).

You have to hit Ctrl-T the *instant* you get the first message from the empeg (the bit that ends "peace..." and pauses for maybe 3/4 of a second). If you miss this, it won't enter the test.

The randomness does look like a ram fault, though.

Mine doesn't even pause for a split second...

Frozen at this point...

- Jon

Hmm, maybe your terminal software isn't quite keeping up. It definitely does pause, and the initial boot (plus the ram test, obviously!) uses no RAM at all so shouldn't be affected by any problems. Is flow control turned off in the terminal program?

Hugo

Yes, flow control is on, and it looks like the term prog is keeping up... It scrolls by so fast. I can't see any pause at all... maybe that's part of the problem?

- Jon

Hmm. Actually, I'm a bit worried about this line in the boot:

iput: device 03:44 inode 1034 still has aliases!

This is referring to hdb4 I think, and a possible filesystem corruption. It's possible that this is triggering a bug in the linux kernel and getting everything very upset. You *should* be able to hit ctrl-c repeatedly during bootup and get the empeg to a shell prompt - if you can, try doing "e2fsck /dev/hda4" and "e2fsck /dev/hdc4" (c4 is the secondary on a mk2's single bus).

As you've opened the unit under tfabis's guidance, you could try disconnecting the second drive (which is where it appears to have the problem) - this is the lefthand one when looking at the empeg with the display facing you. Leave the first one connected and see if it's happier - if so, it could well be ext2 has got itself incredibly confused. We've not seen this before, though, on any linux box!

Hugo

Ok, I'll try your disconnection problem. Control C tries to force the empeg to go into a shell prompt, but it has no shell...

Starting bash.
no søShell exit
empeg-car 1.0.

Should I be running the developers version or something?

- Jon

Flow control (hardware *and* software) should be off - the empeg doesn't do it atm. This is probably stopping you from sending the ctrl-T.

Hugo

Ah yes, you need developer on there. Sorry, I'm so used to running developer (so I can break my unit more easily) that I forget about it... you've tried applying upgrades and it's not happy, yes? In which case, the only option is the second HDD disconnection attempt...

Hugo

Ok, am installing the developers version now...

- Jon

Ok, I'm at the root... can't seem to find the e2fsck program...

Where is it?

- Jon

I will indeed be in touch tomorrow. In general I don't think the BBS is the right place to provide this kind of in-depth support, but since our VPN server is down I guess Hugo found this the easiest place to respond to the issue.

It certainly sounds like a bad RAM chip, which we can swap quickly.

Rob

But we're making progress!!! ARGH!

Can we chat or try to fix this with any other method? AOL Instant Messenger? Fax? Cans and string? email? telephone?

- Jon

If Hugo's still awake and willing, you're welcome to discuss it all night with him. Personally, I'm going to bed - I don't have any technical input to offer anyway!

If I have an email waiting in the morning saying that it's fixed, then I'll be very happy - but if not, I'll make it my business to get your player fixed in the fastest time possible.

Rob

Hugo and I just hung up after he figured out that it was a corrupted partition. Looks like (so far) that everything is running smoothly now...

THANK YOU HUGO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

- Jon

Hugo and I just hung up after he figured out that it was a corrupted partition. Looks like (so far) that everything is running smoothly now...

Wow, past midnight (in England) on a Monday night, and Hugo calls Jon (overseas) from home to tell him how to fix a corrupted partition.

I don't care what anyone says about features, bugs, price, capacity, sound quality, whatever. There is nothing, nothing that beats this kind of customer service and dedication. You can't put a price tag on that.
