It seems that the HP Watchdog timer does not work properly: it triggers
a kernel panic instead of rebooting the server.

The issue came up here in this thread:


At least 3 users seem to have solved the problem by blacklisting the
corresponding hpwdt kernel module.

As remarked by Alexandre, the Ubuntu folks actually decided to black
*all* the hardware watchdog timers some time ago
( https://lists.ubuntu.com/archives/kernel-team/2015-March/054512.html )

Should we add hpwdt to our list of blacklisted module ?
