Hi,
The commit below to ichwd.c, breaks the watchdog on a number
of Intel boards I tried it against. (ICH5 and ICH7) The module
loads, but the box never reboots after sending a sig 11 to watchdogd
ichwd module loaded
ichwd0: <Intel 82801EB/ER watchdog timer> on isa0
Reverting to the version of ichwd.c prior to your commit unbreaks it
and the watchdog works once again in that the box reboots after
killing watchdogd.
