anyone had success with ichwdt?

Adam Montague
I've been having an openbsd machine hang recently (no ddb, you can ping
it, connect to its tcp ports, but it won't do anything).  So I compiled
a copy of GENERIC with ichwdt uncommented to try it out.  Its detected
fine, but neither watchdogd nor using kern.watchdog.auto=1 actually
resets its timer, so it just keeps rebooting itself no matter what.
