Hi,
I just got this with 2.6.22-rc2 + cfs-v13 + swncq patch:

At the time I was creating a DVD ISO image (reads and writes went to the
disk
that was resetted), browsing mail in thunderbird which also exercised
the same
disk and I was downloading another ISO with about 400-450 kB/sec to
another disk. Here are the disks in question:
scsi 0:0:0:0: Direct-Access ATA SAMSUNG HD160JJ WU10 PQ: 0 ANSI: 5
scsi 1:0:0:0: Direct-Access ATA ST3320620AS 3.AA PQ: 0 ANSI: 5
I got almost the same yesterday with 2.6.22-rc2-mm1:

After the system disabled NCQ there weren't any more more ata resets
and the disks were working OK.
Strange thing is, when I have run PostgreSQL pgbench with 25 clients
on 2.6.22-rc2 + cfs-v13 + swncq (which clearly showed advanced transfer
rate)
I had no such problems. The PostgreSQL DB was also on ata2.00.
