>Description:
freeipmi comes with a bmc-watchdog (if you have ipmi/bmc on board)
this uses a hardware watchdog timer, rather then (just) the kernel 'watchdog' daemon. (if the system is locked up, the kernel might not be able to trigger a reboot anyway)
All this patch does is add a ../rc.d/bmc-watchdog rc script.
options taken from Linux freeipmi-bmc-watchdog /etc/init.d/ script.
been using this for several months.
note, there WAS a strange bug in 1.0.5 that made SOME dell systems reset.
this is not the case with 1.0.6.
also note:
it would be MUCH BETTER if the kernel watchdog could soft boot/sync fsys, but failing that, maybe a hard reset is in order for critical systems.
>How-To-Repeat:
na
>Fix:
apply patch. (adds rc script)
not sure if this needs a portsbump, since if someone is already using freeipmi, then don't need to install this.
