ata5: soft resetting port

The CPB resp_flags 0x2 entries are ones where the drive has been sent the request and the controller is waiting for a response. The timeout is 30 seconds, so that means the drive failed to service those queued commands for that length of time.

It may be that your drive has a poor NCQ implementation that can starve some of the pending commands for a long time under heavy load?

Thanks for your answer. That could very well be the problem, as all 4 drives on the sata_nv HBA are older than the sata_sil ones. I'm going to swap them to see if the problem is reproducible on the sata_sil HBA. (see test #2)

- Test #1
I switched the scheduler to CFQ on all disks and ran the file reorganizer all night. In the morning I ended with a drive missing in the array. And lots of SATA port resets, with plenty of 0x2 again, see the attached log.

BTW, you can see around "md2: recovery done" a second disk failed before the first was completely rebuilt.

- Test #2
I swapped all the drives with this scheme: sda->sdh, sdb->sdg, sdc- >sdf,..., sdg->sdb, sdh->sda. So now all the newer drives are attached through sata_nv (ata5:8), the oldest through sata_sil (ata1:4) I kept the scheduler to anticipatory and ran xfs_frs. 60 seconds later it hanged. Still on ata5/ata6, i.e. sata_nv. Drive reconstruction... Then I switched the scheduler to CFQ. xfs_fsr + 10 seconds: another freeze. No drive loss from the array though. See the dmesg below.

So it seems to be either a cabling problem or a bug with sata_nv ? I'm running gentoo's 2.6.20-xen, and maybe my problem looks like the sata_nv/adma/samsung problems reports I can see on the net ?

Thanks !
