We've put a 2.6.29 kernel on these two systems and experienced another kernel oops yesterday. So far, we haven't been able to reproduce it on demand, but it has occurred under a heavier system load each time (load average of 16 with 2,000 blocks/sec every 5 seconds writes to the devices attached using the mptsas driver. The oops from yesterday isn't identical to the previous oops, but the end result is the same where the system has to be rebooted. I've attached that the log capture of the oops. The system is identical to the original specs, just the kernel has chan= ged: # cat /proc/version Linux version 2.6.29.4-0.1-default (root@tile01-primary) (gcc version 4.3.2 [gcc-4_3-branch revision 141291] (SUSE Linux) ) #1 SMP Tue May 26 22:50:58 CDT 2009 Hopefully this is helpful.
