Hi Vojtech, the hid driver oops'es on the BerkshireProducts USB PC Watchdog card when it automatically disconnects itself, just before doing it's reboot stuff. (See Oops log at the end of this message)
The (quick) fix in this case is to add this card to the hid blacklist. (See diff below). I added the change to the linux-watchdog bitkeeper tree (See http://linux-watchdog.bkbits.net:8080/linux-2.5-watchdog ChangeSet 1.1436). Some more info: drivers/usb/input/hid-core.c | 4 ++++ 1 files changed, 4 insertions(+) through these ChangeSets: <[EMAIL PROTECTED]> (03/12/11 1.1436) [USB] hid blacklist addition Added the Berkshire Products USB PC Watchdog to the hid blacklist. This to avoid problems with USB-Disconnects when the card feels it should reboot...
