RestoreCD 4.99.72 & 5.0 BETA boot error

Cobalt Restore CDs 4.99.72 and 5.0 BETA boot on an i386 box fails
exactly the same way...

vr0 at pci0 dev 18 function 0: VIA VT6102 (Rhine II) 10/100 Ethernet
panic: mpacpi_findintr_linkdev: irq mismatch
fatal breakpoint trap in supervisor mode
trap type 1 code 0 eip c042c95c cs 8 eflags 246 cr2 0 ilevel 8
Stgopped in pid 0.1 (system) at netbsd:breakpoint+0x4:  popl   %ebp
db{0}>

NOTE that the boot memu ignores USB keyboard input, so it is impossible
to try other memu options, such as disable ACPI or disable ACPI & SMP.

The 4.0.1 CD appears to boot fine.

Maybe the same problem with PR kern/38540
http://www.NetBSD.org/cgi-bin/query-pr-single.pl?number=38540
It is not fixed yet even in -current, though.

Does your machine have some BIOS memu like "Legacy USB support"?
Enabling it may make BIOS INT functions (which x86 bootloader uses)
also recognize USB keyboard.

Maybe this is a problem in new ACPICA..

Here is something weird when I enable Legacy USB Support:

1) There is no timer allowing me to select a menu. It jumps straight to
zero and claims to boot option 1. Crashes in same place.

2) Reboot once more and between BIOS and Netbsd boot menu, I keep
pressing 3 in the hope that the boot menu will take my option from the
keyboard buffer; output reports boot option 1 selected, YET the system
boots. No crash and no evidence of ACPI being checked. So I assume it
skipped ACPI as desired.

So legacy support appears to help solve the problem, BUT has side effects.

Hmm, but all NetBSD/i386 binaries used in restorecd
(including GENERIC kernel and bootloader) are
just extracted from stock i386 distribution,
so that problem will be handled by x86 or ACPI guys.
