At first I think that my problems was cause I use printf, but changed all of them to log cause it safe to use from interrupt handlers. The situation become better but I still observe system lockup in case I output some debug information from my driver. Also I have some problems with system console via com port. Instead of messages from kernel I see the first letter of the month name. Could anybody comment my observation? Does anybody saw anything like this? Oh, I forget to say I observe that with both Current and Releng5, SMP. Also I can't trigger NMI so I can't see the point of lockup. rik
