ata breakage [STILL]

I am still getting breakage from ata with sources from around midnight
CDT (after the latest updates). These result in odd messages being
printed to the screen and eventual panics before the machine mounts
root. See the attached horrific.txt for the boot messages and some
brief ddb action. Note the garbage right before the panic. The garbage
was printed out before a 30 second pause prior to the panic.
I backed out src/sys/dev/ata to '2005-05-03 07:55:00 UTC' and everything
works perfectly. See the attached normal.txt for these boot messages.
The panic seems to happen during probing of the CD drive. I use
atapicam *without* atapicd. The kernel config is also attached.
