Hi, 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.
