The following error consistently appears at apparently random intervals in syslog:
kernel: ata1.00: exception Emask 0x2 SAct 0x1001 SErr 0x0 action 0x2 frozen
kernel: ata1.00: (spurious completions during NCQ issue=0x0 SAct=0x1001

kernel: res 40/00:00:39:2b:cc/00:00:08:00:00/40 Emask 0x2 (HSM violation)
Controller is ATI SB600 using the AHCI driver.
64-bit DMA is disabled.
Disk is:
ata1.00: ATA-7: ST3160812AS, 3.ADJ, max UDMA/133
Can't we just turn off NCQ automatically when this happens?

After sever such occasions, NCQ will be turned off automatically.
Hmm... It's a bit surprising to see this on a Seagate drive tho. Can
someone crosscheck this by attaching the drive to an intel ahci?

After upgradin kernel on one of my firewallas (2.6.14->2.6.20) I noticed
similar problem with another Seagate: ST380817AS connected to ICH6.

Disks are working in software (MD) mirror. Disabling NCQ for both disk
by adding '{ "ST380817AS", NULL, ATA_HORKAGE_NONCQ, },' solved my
issue - there are no more resets.

Can you please give a shot at 2.6.22-rc7? The log you posted lacks
information about why it's happening.
Thanks.
