I'll go look. Look at the value of cr.ifa - something is badly wrong here. I got panics like this a couple of times when I was starting the interval timer before registering the timecounter and I got a hardclock interrupt before the timecounter was fully initialised. I though I fixed that though - what is the stack trace here?
