Thanks Mark - I've finally gotten this patch applied.

With smartd disabled and no smart commands issued, a readonly badblocks
scan of /dev/sdb2 shows no problems and now gives:
Feb 25 10:38:31 haze kernel: ata2: status=0x51 { DriveReady SeekComplete
Error }
Feb 25 10:38:32 haze kernel: ata2: no sense translation for op=0x28
status: 0x51
Feb 25 10:38:32 haze kernel: ata2: status=0x51 { DriveReady SeekComplete
Error }
Feb 25 10:38:35 haze kernel: ata2: no sense translation for op=0x28
status: 0x51
hundreds of times.

and during boot I can get:
ata2: no sense translation for op=0x28 status: 0x51
ata2: translated op=0x28 ATA stat/err 0x51/00 to SCSI SK/ASC/ASCQ 0x3/11/04
ata2: status=0x51 { DriveReady SeekComplete Error }
Installing knfsd (copyright (C) 1996 okir@monad.swb.de).
ata2: no sense translation for op=0x28 status: 0x51
ata2: translated op=0x28 ATA stat/err 0x51/00 to SCSI SK/ASC/ASCQ 0x3/11/04
ata2: status=0x51 { DriveReady SeekComplete Error }
ata2: no sense translation for op=0x28 status: 0x51
ata2: translated op=0x28 ATA stat/err 0x51/00 to SCSI SK/ASC/ASCQ 0x3/11/04
ata2: status=0x51 { DriveReady SeekComplete Error }

Subsequently a
 smartclt -data -a /dev/sdb
shows no errors.
So could this be a faulty disk that smart shows is OK and shows no read
or write errors?

The other problem I noticed was that
 smartctl -o on -data /dev/sda
still just gives:
Feb 25 10:51:47 haze kernel: ata1: PIO error
Feb 25 10:51:47 haze kernel: ata1: status=0x51 { DriveReady SeekComplete
Error }
Feb 25 10:51:47 haze kernel: ata1: error=0x04 { DriveStatusError }
Feb 25 10:51:47 haze kernel: ata1: PIO error
Feb 25 10:51:47 haze kernel: ata1: status=0x51 { DriveReady SeekComplete
Error }
Feb 25 10:51:47 haze kernel: ata1: error=0x04 { DriveStatusError }
Feb 25 10:51:47 haze kernel: ata1: PIO error
many times.

I get similar problems for all the drives under both sata_sil and sata_via.
