Hello everybody,

I upgraded to today's -CURRENT and upon reboot with the new kernel,
experienced a panic. Since I did not see it reported here yet, here is
some info. More available on request, but I do not have a serial console
and therefore had to transcribe everything by hand. Also, there was no
core dump. (How can I force it?)

dmesg is not available from the failing kernel, but the only "could
sleep with..." messages came from the soundcard driver.

The panic happens also in single-user mode, in my case most easily
triggered with the use of rm(1).

If you need any more info, just ask.
