freebsd stable - Apr 2006 - USB & ACPI getting better but not quite there - IBM T42p

Hi,

I was delighted to see that my laptop now wakes up fine when booted from
an external USB disk with 6.1-RC1 (actually RELENG_6_1 supped
yesterday).  I had inadvertently suspended, and it did come back up when
hitting the power switch! It subsequently hung when I switched into X,
but I think that's a problem with DRI.  I saw it as well when booted
from the IDE disk, and it went away after disabling DRI.

But the other problem with powerdown when USB-booted is still there.  If
I hit the power switch it shuts down ok and dismounts all filesystems
but then it sits there, doesn't remove power.

All works fine when booted from the internal IDE disk, it hangs only
when booted from the external USB one.

Hmm, I regret to follow up that this only works in rare cases.  Most of
the time the machine hangs during suspend, or runs into USB timeouts
(umass0: BBB reset failed, TIMEOUT), or both -- I'm not sure, I may have
been impatient before seeing the USB timeout message sometimes.

Also on one occasion where the suspend did work I then power cycled the
disk before resume, and then at resume I got a panic about not being
able to access the disk.

So I guess I was wrong with about 98% of my statements :-(  -- it
doesn't work yet.
