Please test and/or review a new watchdog driver for watchdog timer found in
SB600 and SB7xx south bridges, and also for watchdog hardware
advertised/described via WDRT ACPI table.

A tar file with the source file and module Makefile:
http://people.freebsd.org/~avg/amdsbwd.tgz
A full diff of the new driver against head source tree:
http://people.freebsd.org/~avg/amdsbwd.diff

If you have the mentioned hardware or if your ACPI provides WDRT table, please
try this driver. WDRT presence can be checked with this command:
acpidump -t | fgrep WDRT

I am interested in what the driver prints to dmesg with debug.bootverbose=1, if
it succesfully attaches and, obviously, if the driver does its job (i.e. resets
system on timeout).
That could be tested, for example, in single user mode with this command:
watchdog -t 4

Thanks!
