Im having some issues on a brand new Supermicro server that we have
running in production along side a few other machines which are
identical to this server..
The output from the netconsole attached to the server is here:

Once this starts, a couple of minutes goes by and the machine locks up
completely.
I have been unable to locate the problem here, anyone that can point me
in the right direction?

Looks there is a deadlock trying to hold the device_lock or hash_lock. anything
abormal print out before the NMI watchdog? What is running in the machine?
Looks this is old kernel, is it possible you can try a latest kernel and report
back?
Thanks,
Shaohua

The server is hosting plain VPS's, there's a few that use it for
rtorrent which is quite disk extenssive, but from what I can see that
iowait is quite low.
There's absolutely nothing logged at all before the lockups, everythings
running fine and then suddenly it just crashes, im beginning to think we
might have a hardware problem, but im having a hard time finding the
actual issue.
Any ideas?
Best regards

Daniel,
This is one of those hard problems to diagnose. Can you take the
system out of production and run some stress tests on it to see how it
does?
Have you updated all the firmware on the board? Have you disabled
hyperthreading as well? Is there any overclocking or stuff like that
happening? If so, go back to the BIOS "safe" defaults.
Do you have another system with the same hardware that's working fine
in the same type of setup? Then that does point to hardware.
Is your power supply maxed out or near the limits? Maybe you're
getting a slight under-voltage? Not likely... but you never know.
And why is the kernel tainted? Are you adding in third party modules?
If so, remove them completely from the system. SuperMicros don't
generally require anything like that in my experience.
Is it some of the extra monitoring modules you have installed?
Good luck!
John

Hi,
Well, things have gone from bad to worse in my eyes..
We have had the following hardware replaced: Chassis, Motherboard, CPUs,
RAM, SAS Cable, SAS Controller and the PSUs, basically we are down to
just the harddrives and it is still crashing..
This is a rather long one :)

LOCKUP on cpu 4
We are not using any additional modules for monitoring the servers other
than plain ping warnings in case a server is not responding..
We have tried loading the optimized defaults in bios, the current
motherboard is on an older bios just for testing and the problem is
identical..
I just cannot find the problem here, it appears to die constantly.
Right now, i have taken it out of production, and im moving data over
from that raids, it currently consists of 6 raid5's, i will move data
between them one at the time and re-create the mdadm raid and the
filesystem on them to see if there's a problem there.
Any other ideas?
Best regards
Daniel
