Kernel error kernel:[360783.353677]

[Arcesilaus]

Thanks for the offer: I have to find a way to post the latest Logs here (if that is permitted).

Well, the freeze is quite comprehensive: no response on NICs (not able to ping), no response on console (no keystroke wakes the screen) at all.
All that is left, is a hard reset.

hm okay this is definitely a kernel panic.
just upload the logs anywhere and post a link to it? should be permitted

Hi Daniel

It looks indeed like a kernel panic, mostly happening under some load. I've checked the logs for the latest connection logs before (manual) reset, and here are the results:

26-10, 02:00: Freeze when scanning folders for music files, logs taken at 07:13:

24-10, 16:10: Freeze when re-applying security rights, logs taken at 16:50:

Admittedly, when bringing the machine back up, I did not always run the filesystem check: there was simply not enough time for that.
Could any FS errors cause a kernel panic?

Hi,

normally not.

Please send us the following logs completely(!):

critical_error, dmesg2, test, Samba

Greets

I just posted you a message on your profile page that contains the details of where the log can be found.
Please let me know if you are successful in picking them up...

[danielweeber]

Strange. Do you have any spare memory for that machine?

[Arcesilaus]

I don't, but I could take out 1 module (4GB remaining), although I wonder: a full pass on memtest did not reveal any errors.

There are only 3 things remaining that I can think of:

1. Now that I recall: I disabled the APM and ACPI boot options, but two (?) other were still enabled. Would it be worth a try to turn them off?
2. Could it be a problem with the USB DOM that hosts the OS? I could try running on another USB device.
3. Would it be worth a try to run a previous version that ran stable for a long time, i.e. v6 update 90? Are there any known changes that could cause this random freeze?

P.s. I just saw by the inability to reach my website that the machine froze again, this time after only a few hours - it's slowly getting hopeless...
