Should I send-pr this?

Kernel is:
NetBSD eros.endersgame.net 1.6M NetBSD 1.6M (EROS) #436: Mon Jan 20 18:25:1=
2=20
EST 2003     dive@eros.endersgame.net:/sys/arch/i386/compile/EROS i386

from sources cvs updated about a minute before building the kernel.
userland is from 20030118.

I can make the kernel, core, and/or config file (or any other pertinent fil=
es)
available if they would aid tracking this bug down...
This is the second panic I've had, with the same backtrace, since nathanw_s=
a was
merged.

Jan 21 21:45:50 eros savecore: writing core to /var/crash/netbsd.2.core
