kernel crash - fc6

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



   Today my main server crashed - 2 processor SMP machine. I'm embarassed to 
say I'm not sure which kernel but I suspect it was kernel-2.6.20-1.2933.fc6.
 It rebooted fine (now on 2948) - got several partitions fsck'd due to not 
being checked in 203 days.

   It has 2 xeon processors each:

vendor_id       : GenuineIntel
cpu family      : 15
model           : 1
model name      : Intel(R) Xeon(TM) CPU 1.70GHz
stepping        : 2
cpu MHz         : 1694.884
cache size      : 256 KB



 Here's what I got in the log file:

 System has a bunch of scsi disks.
