Hey, I have same problem with my old computer:

atapci0: <Intel PIIX4 UDMA33 controller> port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xf000-0xf00f at device 2.1 on
pci0
ata0: <ATA channel 0> on atapci0
ata0: [ITHREAD]
ata1: <ATA channel 1> on atapci0
ata1: [ITHREAD]
ad1: 76319MB <WDC WD800JB-00JJC0 05.01C05> at ata0-slave UDMA33
acd0: CDRW <CD-W540E/1.0C> at ata1-master UDMA33

Also, it waits 10 seconds after "ata0: <ATA channel 0> on atapci0", true ?

If you reboot 3-4 times it will pass and everything will work
normally. Then, I tried with disabled ACPI and it booted always
without problems. However, then I recompiled GENERIC kernel because of
HPLIP and now situation is opposite: it always boots with ACPI but not
with ACPI. Very strange...
