Got any kernel coredump or backtrace? the panic isn't super informative.
I see that crash(8) is somewhat limited on alpha (so not sure if it does
kernel core dumps at all), but on amd64 you should be able to do:
And if there's a netbsd.1.gz there:
crash -M netbsd.1 -N netbsd.1.core
Also if you do:
gdb /netbsd # even better if it's the netbsd.gdb built from the same
# sources. It's in the kernel build directory.
# e.g. obj/sys/arch/alpha/compile/GENERIC/netbsd.gdb
(gdb) info line *(0xfffffc0000bc2d0c)
^^ this is the value mentioned as 'ra'.
it should be the function calling into this
one, so it's part of the backtrace
What function is it?
