Hang while booting today's -CURRENT (ATA related?)

[Joe Marcus Clarke]

I have a Dell Precision 360 workstation (i386) with an ATA DVD-RW drive
and an SATA Seagate drive.  After a long time (Feb 14, 2008), I supped
-CURRENT, and rebooted.  Now the box hangs in what appears to be a probe
of the ATA devices.  Here are the last few lines of the verbose boot
(copied from screen):

ata0: identify ch->devices=00000000
ata1: identify ch->devices=00010000
The GEOM class LABEL is already loaded.
ata1-master: pio=PIO4 wdma=WDMA2 udma=UDMA33 cable=80 wire
acd0: setting PIO4 on ICH5 chip
acd0: setting UDMA33 on ICH5 chip
acd0: <HL-DT-ST DVD+RW GRA-4120B/F114> CDRW driver at ata1 as master
acd0: read 6890KB/s (6890KB/s) write 6890KB/s (6890KB/s), 2048KB buffer,
UDMA33
acd0: Reads: CDR, CDRW, CDDA stream, DVDROM, DVDR, packet
acd0: Writes: CD, CDRW, test write, burnproof
acd0: Audio: play, 256 volume levels
acd0: Mechanism: ejectable tray, unlocked
acd0: Medium: no/blank disc
ata2: identify ch->devices=00000000
ata3: identify ch->devices=00000001

That's it.  After the DVD drive, the only other ATA device is the
SATA-attached Seagate disk which is master on ata3.  The previous
kernel's verbose boot reported:

ata3-master: pio=PIO4 wdma=WDMA2 udma=UDMA133 cable=40 wire
ad6: 152627MB <Seagate ST3160815AS 3.AAD> at ata3-master SATA150
ad6: 312581808 sectors [310101C/16H/63S] 16 sectors/interrupt 1 depth
queue

This drive is located on a Promise controller:

atapci0: <Promise PDC20375 SATA150 controller> port 0xcc00-0xcc3f,0xcbf0-0xcbff,0xcc80-0xccff mem 0xfe73f000-0xfe73ffff,0xfe740000-0xfe75ffff irq 22 at device 1.0 on pci2
...
ata3: <ATA channel 1> on atapci0

Any ideas?  Thanks.

Joe
