Hi all, I wanted to add a watchdog timer that would reset my VMs if they hang or stop responding. I managed to enable an Intel 6300ESB ICH watchdog, however I note it isn't being picked up by the ichwdt driver:

Alternatively, how can I help with ichwdt? Regards, -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.
