What processor (x86) type/configs is your kernel compiled for?

Can you repeat with Magic SysRq enabled (if not already) and
set log level to 9 (echo 9 > /proc/sysrq-trigger or
Alt-SysRq-9).  That should provide more console log info
for us.... then post that log.  (or check your log files,
this log info may already be in some of them)

Thanks,
