I cvsuped and built a new world and kernel yesterday at approximately
11:00 EST, 16:00 GMT.

During reboot to the new kernel, it hung on the CD drive with a DVD in
it.  I think it has done that with earlier kernels too, but I don't
often have a disk in the drive.  I tried again with an audio CD in the
drive and it also hung.  I manually wrote down the verbose dmesg about
the hang but left it at home this morning.  It boots just fine without
disk in the drive.  I didn't have a data disk within reach and didn't
test that combination.

Today I tried to burn a 5.2-RELEASE ISO so I can test the ida controller
in one of my Compaq 1850Rs.  I see the same (I think) dmesg output and
the burncd process is hung waiting for disk io.

acd0: WARNING - WRITE_BIG interrupt was seen but taskqueue stalled

To my memory, that is exactly the output that I got when booting with a 
DVD in the drive with the exception that of "sed 's/WRITE_BIG/READ_BIG/g'".
With the audio disk, I think it was READ_CD but I'm not sure exactly.

This is a Compaq Presario 2195us.

With this kernel, I've had a panic on shutdown and a hang on shutdown.
I was in a hurry both times.  Those are the only two times I've shutdown
with this new kernel.
