Crash system!!!

["Alex Feldman" <al.feldman@sangoma.com>]

Hello

I'm writing Device Driver under OpenBSD for our Network adapters.
I catched the case when I had kernel crash. It's really hard duplicate (you
will need our hardware and driver), but this is what happened:

* The crash happened on ADSL driver. The driver has software timer that
running every ~1 second.
During this time I calculate statistics/check the line status. Everything
looks find, except one place:
	if (ticks > hz * 0.2)

if I change this line to
	if (ticks > ((hz * 2) / 10)

everything is perfect.
I can't send you memory dump because computer is just freeze.

If you need more information, please let me know.
