panic, acpi-related apparantly, on todays current

Hi there,

I went top of tree on my Compaq EVO N160 laptop today.

The newly built kernel panics with roughly the following
messages printed (no serial port on this laptop unfortunately so
hand-transcribed):

...
acpi_acad0: acline init start
acpi_acad0: On Line  		<-- running from battery shows offline, 
				<-- the panic remains
acpi_acad0: acline init done, tried 1 times
ata0 master: pio <bla bla>
Sleeping thread (tid 100024, pid 20) owns a non sleepable lock
sched_switch..
...
<panic>

Disabling acpi via hints makes the panic go away.  A kernel from approx
March 15 works fine.

Anybody else seeing this?
