npxdna vector not initialized

[Erik Bertelsen <bertelsen.erik%gmail.com@localhost>]

On my Mac Mini, I have been unable to boot recent custom-built kernels.
My latest working kernel is from 6 Sep 2010, and my earliest saved
non-working kernel is from 10 Sep. Since then (and up to a few minutes
ago) I have made several unsuccessful attempts to boot new kernels.

The newer kernels panic after the device probes as shown below:

On-screen messages up to panic (retyped manually):

(device probes)
boot device: wd0
root on wd0a dumps on wd0b
root file system tyep: ffs
panic: npxdna vector not initialized
fatal breakpoint trap in supervisor mode
trap type 1 code 0 eip c015ac24 cs 8 eflags 46 cr2 8066b80 ilevel 0
Stopped in pid 2.1 (sh) at           netbsd:breakpoint+0x4:  popl      %ebp

There is not much I can do at this stage as the keyboard is not yet
functional. Because of the non-working keyboard I also cannot do
anything in the boot menu -- and my only way to recover is to boot an
older install CD and used that to mount the root partition and rename
the working kernel back to /netbsd.

Can anyone explain what change to the system causes this and/or give
suggestions on how to correct or circumvent the problem ? Is it
related to npx attaching to ACPI and not to isa0 ?

kind regards
- Erik
