Yes it does

Yes.


I tried again to run it on one of the boxes in 
zoo.freebsd.org.  I enabled the watchdog in the 
BIOS and I know it kicks in. On this motherboard, 
if you enable the watchdog in the BIOS, the box 
will reboot in 4min after posting no matter what, 
unless the watchdog is properly loaded and 
set.  However, neither your version nor the one 
in the PR works. It kld loads in both cases, and 
I can startup watchdogd, but the box will reboot in 4min no matter what I do

ichwd module loaded
ichwd0: <Intel ICH7 watchdog timer> on isa0
ichwd0: Intel ICH7 watchdog timer (ICH7 or equivalent)

and same with the version from the PR.

leopard3# kldload /tmp/ichwd.ko
ichwd module loaded
ichwd0: <Intel ICH7 watchdog timer> on isa0
ichwd0: Intel ICH7 watchdog timer (TCO version 2)
ppc0: parallel port not found.
leopard3# watchdogd -t 20
leopard3#

But if I startup watchdogd (it seems to be 
running), the box ends up being rebooted in 4 
min.  If I kill -9 watchdogd, it still reboots in 4min, and not any quicker.



But my other ich7 box works as expected (kldloads 
and box reboots after doing a kill -9 on watchdogd)
