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: May 12 12:25:52 srv01 kernel: BUG: soft lockup detected on CPU#0!
