NetBSD/i386 panics


I've experienced occasional panics under NetBSD/i386 current this I upgrade
my system last weekend. Today I finally managed to get a panic message:

WARNING: module error: module `k_helper' not found
WARNING: module error: module `k_helper' not found
fatal privileged instruction fault in supervisor mode
trap type 0 code 0 eip d2a1b000 cs 8 eflags 10292 cr2 bb827000 ilevel 0

Skipping crash dump on recursive panic
panic: trap
Faulted in mid-traceback; aborting...rebooting...

Unfortunately "gdb" cannnot tell where the kernel crashed:

tron@lyssa:/src/sys/compile/LYSSA>gdb netbsd.gdb

(gdb) disass 0xd2a1b000
No function contains specified address.

Has anybody else seen this?

        Kind regards
