kernel panicing - linux sysrq capability

Jiri B-2

IIUC we can panic kernel via writting to 'ddb.trigger' and
if we have 'ddb.panic=0' it would reboot.

But IIUC we are not not able to control what would happen
during this kernel panic in non-interactive mode, am I right?

I am asking because I'm working on porting corosync/pacemaker[1]
- HA stuff - and they make kernel panic[2] on Linux with 'b'[3] (immediate
reboot the system without syncing or unmounting them) or 'c'
(performing a kexec reboot in order to take a crashdump) under
some conditions.
