Hi! I checked the machine for memory errors with memtest86+, I checked the fans and the general operation, and everything seemed to be alright. The only thing that was surprising was that according to memtest86+ the L1 cache is bigger than the L2 cache (128k vs 64k), but I think that that's because the motherboard is older than the CPU.
Today, after a week of correct working, I got 2 oops again. It occurs again at lock_kernel+0x10/0x32, but this time there's no nfs in the stack trace, so it seems that the problem is elsewhere. Please tell me if there's something I might do to find the actual reason for the bug. I'm including the output of cpuinfo, in case it's helpful, and the kern.log output for the oops: Linux aquadrelli 2.6.18-6-k7 #1 SMP Sat Jan 26 10:03:58 UTC 2008 i686 GNU/Linux processor : 0 vendor_id
