ichwdt* at pci?
DESCRIPTION
The ichwdt driver supports the watchdog timer of the Intel 6300ESB I/O
Controller Hub.
ichwdt provides the standard watchdog(4) interface and may be used with
watchdogd(8). The watchdog timer can be configured via sysctl(8).
Once the watchdog timer resets the CPU, the driver reports it on the next
boot displaying the ``reboot on timeout'' message in the dmesg.
