Ingo,
Is there anything else that needs to be set in the kernel config for the nmi watchdog to trigger?
I ask because I just had a hang but nothing showed on the _serial_ console - I waited a couple of minutes before rebooting.... Is there any other way to verify the watchdog is working? I seem to need X active with mix of 32 and 64 bit applications active to get hung here. A massivily threaded 64 bit java app along with 32 bit firefox and a wine active will eventually trigger things here. If I had to guess I would say that it the switch from 32 to 64 (or vise versa) that triggers the isuue.
TIA & test/debug patches welcome, Ed Tomlinson
