panics during installation of -CURRENT on Thinkpad A31p

Hi,

I just got a Thinkpad A31p on which I try to install -current.

I've tried several snapshots:

5.1-RELEASE panics during kernel boot, while trying to
create a firewire0 device. ACPI enabled or not makes
no difference.

A current snapshot, like 5.1-CURRENT-20031015-JPSNAP
boots correctly and sysinstall starts. A trap is encountered
as soon as I try to configure any of the two network interfaces.
fxp0 and a wi0 are detected. 
ACPI enabled or not again makes no difference.

If I try to configure them using DHCP or even manually
configure them, I get traps like the following:
[..]
kernel: type 18 trap, code=0
stopped at  cbb_intr+0x22: movl %eax,%esi
db> trace
cbb_intr(c2114e00,0,c083b22c,230,c4bfd000) at cbb_intr+0x22
ithread_loop(c4c07980,d7963d48,c083b09e,314,0) at ithread_loop+0x192
fork_exit(c0623c60,c4c07980,d7963d48) at fork_exit+0xcf
fork_trampoline() at fork_trampoline+0x8
--- trap 0x1, eip = 0, esp = 0xd7963d7c, ebp = 0 ---

This one was encountered while trying to set up fxp0 with DHCP.

4.9-RC2 seems to work flawless on this hardware. I can use
both fxp0 and wi0 interfaces. However I would prefer to run
5.x, and I guess you folks would like to have feedback about
configurations resulting in panics.

Thanks and best regards,
 Daniel
