I also got this panic several times in the last hour while compiling
some ports. I cvsuped sources about 10hours ago and buid a new kernel.
Yesterday i was able to build world an mozilla without any problems.
I don't have debugging on at the moment. I'll try building an new kernel
with debugging on. I don't have any experience with debugging. Will an
additional traceback show any additional usefull information?
regards,
flo
