today's 6.1 would not boot here

Hello!

My amd64 system was running:

	6.0-STABLE FreeBSD 6.0-STABLE #5: Sun Nov 20 20:06:48 EST 2005

since the above date quite happily. I've rebuilt world and kernel today
and tried rebooting.

The 6.1-PRERELEASE boot hangs solid (not even Scroll Lock/Page Up is
possible) after printing (in verbose mode):

	pcm0: measured ac97 link rate at 48161 Hz, will use 48000 Hz

I'm attaching the 6.0's dmesg.boot -- in it, the above message is
followed by the ciss-driver messages, but I have no idea, where the
hang is.

I don't think, ciss was modified much in the last 3 months, but the
audio drivers underwent some work, apparently...

This obviously is a show-stopper for me -- probably, for some others
too... Thanks!

Yours,

	-mi
