I finally saw my first -current panic in more than 5 months (not a bad
track record).
I have a panic that I can duplicate with a 24 hour old "make world"
and a 4 hour old -current kernel. If I run the linux netscape (installed
from ports less than a week ago), the kernel panics in copystr().
Minimal gdb output follows. I'll have to generate a kernel with
debug info for more information.
The linux netscape worked fine with my old kernel from 9/16.
I'm willing to try and track this down, but I hope someone
will pop up and have an idea what is wrong.
