This looks like the same panic I reported yesterday but I'm running
6.3 patch 2. I have seen these crashes on my box since 6.3
pre-release, randomly, but under load. My box is based on a
SuperMicro motherboard running Intel Xeon processors. The only
commonality is that we're both using Sata drives.
John, a question, how is swap set up on your system? I was swapping
to a file (a memory disk device /dev/md0). I was doing this because
for some reason lost in ancient history, this machine was not set up
with a real swap partition. Hence, no crash dump.
Last night I repartitioned a second disk, set up a real swap partition
and now I'm currently waiting for this to happen again so I can get a
crash dump.
