Hello. Hope you find this useful.
Posting to you after reading Documentation/oops-tracing.txt
I am still looking into how to report this fault to SUSE.
OS upgraded by SUSE SP2 (latest) CDROM. Cannot get online
update to work to see if newer patches available.
System has 2 x Intel P4/Xeon EM64T cpus. Hyper threading so seen as 4
cpus. Production server in core network for a Telco in Australia. Not
looking good since I lobbied hard to put in Linux instead of Solaris.
After this oops, the machine kept running (phew!), however these
processes hang: ps, top, w. However vmstat, iostat and uptime still
work ok. uptime says machine has a load average of around 20, but vmstat
and iostat say machine is near idle. We will reboot it with nosmp until
this fault is better understood.
dmesg output:
