Hang while hardware probing in 4.8

I have what appears to be the same problem.  I'm a longtime FreeBSD user.  I
put 4.8 on a new laptop (Tecra M1) and when I created a kernel with support
for power management and the sound card, it would hang on the boot in a
similar fashion.  The generic kernel would boot fine.

I found that if I remove the sound support from the kernel (but do have apm
support) then it boots fine.

I haven't had time to experiment further (other versions, more refined
variations in the kernel config, ...). So, for now, I live without sound 8^(
but I'd like to get it fixed.

(So, Sanjay, if you're using the GENERIC kernel, this doesn't help much).

One more possibly related observation.  I've found that if I boot XP and
then return to FBSD then the first time my modified kernel won't boot but
the generic one will!  After booting the generic kernel then I can boot
mine.  I'm at a loss on this unless perhaps Toshiba has XP mess with devices
in some inappropriate way.  Again I haven't investigate further.
