Hi,
Whenever I try to boot my desktop workstation with FreeBSD, it suddenly just 
hangs there forever. When I boot into safe mode, however, I get this in the 
dmesg:
Jun 18 16:01:46 b00b kernel: ad8: 114473MB <Seagate ST3120022A 3.06> at 
ata4-master PIO4
Jun 18 16:01:46 b00b kernel: ad8: FAILURE - READ timed out LBA=234441585
Jun 18 16:01:46 b00b kernel: ad8: TIMEOUT - READ retrying (1 retry left) LBA=0

LBA=0
Jun 18 16:01:46 b00b kernel: ad8: FAILURE - READ timed out LBA=234441644
Jun 18 16:01:46 b00b kernel: ad8: FAILURE - READ timed out LBA=0
Jun 18 16:01:46 b00b kernel: ad8: FAILURE - READ timed out LBA=234441585

The hard drive is connected to an onboard Promise FastTrak (atapci1: <Promise 
PDC20376 SATA150 controller> port 0x8000-0x803f,0x7800-0x780f,0x7400-0x747f 
mem 0xab800000-0xab800fff,0xab000000-0xab01ffff irq 11 at device 14.0 on 
pci0) controller on my Asus p4s8x motherboard. The drive itself is connected 
to the optional PATA connector, which works wonderfully in Windows.

I've currently managed to install Xorg and KDE on the box, all entirely in 
Safe Mode, but the performance is really bad, or not as good as it should be 
on a PC with a Pentium IV 2.4GHz and 1GB PC3200 RAM.
Googling yields irrelevant results to my case, and search results for "freebsd 
p4s8x" (no quotes) indicate that FreeBSD should be working OK with my 
motherboard and all of its native components.

So, does anybody know how to
a) Fix this issue (or, if not)
b) How to prevent a specific device (atapci1 or ad8) from being loaded during 
boot time? Again, googling yields no results, but I might be querying the 
wrong strings.

Attached is my dmesg.boot

Thanks for any help.
