Topic: Ubuntu mining rig debugging (Read 1365 times)
dunand is pointing you in the right direction. Bring the system back up and immediately check the messages in the files in /var/log (you can see the most recently modified files with "ls -lt | head -50". The time it reports next to each file is the time the file was last modified. You can read a file with "less ." Do ">" to go to the end of the file.) Report back anything interesting you find there.
I would suspect too aggressive overclocking and/or a PSU pushed to the limit.
I had the same problem with ubuntu 11.04. It was very annoying. I was having a system crash every 2 or 3 days. I changed the ram stick to fix it.
there was an error message in /var/log/kern.log or syslog (can't remember which one) just prior to crashing.
The error message was : "unable to handle kernel paging request".

Hi,
My ubuntu mining rig (2x6970; 1x 5830; 1x 6870) running pheonix on bitcoins.lc is crashing one or twice a week (I reboot and restart when it happens)...it's stable enough that I didn't do anything about it so far but it's getting irritating in the long run. Warmest card is at 79ºC (6970), coolest (5830) at 60ºC. When it crashes the screen simply goes black.
What would be the right way to debug this? Is there a way to log what happens or my only hope is to tweak my pheonix settings?
Thanks,

When these things happen to me, I usually just back the clocks down a little to see if it stabilizes and move on. It is better to run a little slower and never crash then get a couple of more Mh and have to deal with it.
