>Environment:

This is a very unusual configuration:

- NetBSD/hp300 on a 340
- running serial console over dca0
- running diskless with root over nfs
- running the Xhpux X server (under COMPAT_HPUX) on the topcat display

The -current sources are some weeks old, so I will be updating and
trying again RSN.

>Description:

While the X server is running, type 'reboot' on the serial console to
see:

Dec  8 12:07:02 reboot: rebooted by root
Dec  8 12:07:03 init: kernel security level changed from 0 to 1
panic: kernel diagnostic assertion "bytes != 0" failed: file "/rdrive/netbsd/cur
rent/src/sys/miscfs/genfs/genfs_vnops.c", line 1330
