... OK, this did the trick, i got into db.
I managed to get a vmcore, and there is a kernel.debug
avail.
I included below the output of some commands i ran
in db, can someone suggest what else i might run next
time?
Is anyone interested in having access to this vmcore & kernel.debug?
Or can suggest where i might look in it to find this lockup?
The system was locked up, so when i pressed the key
sequence to enter the debugger, it timed out stopping
the other cpus. Everybody is in sched_switch and idle???
