Kernel Locks During Device Probe on 7.0 Current

I've been tracking 7.0 for several weeks now using
cvsup. Unfortunately, in this time, I haven't been
able to build a working kernel, even using GENERIC.

When I try to use a 7.0 current kernel, the system
gets about 6/8ths through the device probe, then
simply stops. It does not visibly panic; it just stops
the device probe and does nothing. (It acts like the
kernel goes into a loop someplace and never gets out.)
This occurs whether ACPI is enabled or not.

Unfortunately, the hang occurs before the system can
enter even single user mode, making a post of the full
device probe impossible. I've tried to reproduce the
five lines proceeding the hang to give an idea of
where it's stopping.

Using the stock GENERIC kernel configuration with
verbose logging and ACPI enabled, it stops boot right
after printing:

lo0: bpf attached
rr232x: nfirewire 0: 1 nodes, maxhop <=0, cable IRM =
0 (me)
firewire 0: bus manager0 (me)
o controller detected.

Compiling GENERIC without Firewire (but with ACPI
enabled) gives:

rr232x: no controller detected
acpi_acad0: acline initialization start
acpi_acad0: On Line
acpi_acad0: acline initialization done, tried 1 times
battery0: battery initialization start
battery0: battery initialization done, tried 1 times

When ACPI is disabled, the GENERIC kernel hangs right
after printing:

lo0: bpf attached
rr232x: nfirewire 0: 1 nodes, maxhop <=0, cable IRM =
0 (me)
firewire 0: bus manager0 (me)
o controller detected.

When I try to run GENERIC without ACPI and without
Firewire compiled in, I get:

lo0: bpf attached
rr232x: no controller detected

followed by the kernel hanging.

FreeBSD 6.2 runs very well on this machine, and the
output of pciconf -vl is:

love to be able to start using FreeBSD 7 on it. Thanks
in advance.
