-10.0_BETA panics when system is rebooting

[BERTRAND Joël <joel.bertrand%systella.fr@localhost>]

	Hello,

	I have patched my main server with if_tap.c patch. tap0 now runs as
expected but, when I have restarted system (that ran with a -10.0 BETA
kernel without this patch), it panics with :

[ 856605,000596] acpiout5 at acpivga0 (DD.5961966] dump device bad

	I don't understand last line as dmesg indicates :
[     3,718620] boot device: raid0
[     3,718620] root on raid0a dumps on raid0b

	Unfortunately, I have replaced netbsd and netbsd.dbg by two new kernels
and I cannot debug. I don't know if this kind of panic is already known.
Next time I can reboot this server, I will try to obtain more information.

	Regards,
