That's flush timing out, which isn't good.

1. Are the errors localized to ata6.02?
  

I think it's ata6.01

The above message says 6.02 tho.  Anyways, if the errors are localized
to one drive, please swap that drive with another drive.  Do the errors
follow the drive or stay with the slot?

2. Is FLUSH always involved (ie. is cmd always ea)?
  

yes

Hmmm... okay.  That sounds like a dying drive to me.  What does
'smartctl -a /dev/sdX' say?

3. If you disable NCQ, what do errors look like?
  

I put all disk-drives in the blacklist , without a change

So, NCQ isn't the problem.

ATM, it sounds like a dying drive to me.  Please double check the errors
are localized to one drive, check smartctl log and try to verify as
written above.

Thanks.
