Promise SATA 300 TX4

I have a machine with 4 of these controllers. And 16 500GB Seagate disks.

 

I installed the snapshot from 200706 to play with zfs, and everything seemed
to work okay.

Then I tried to update to the newest current, and started to get the
following errors when reading from the pool.

 

ad22: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing
request directly

ad22: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing

ad22: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing

ad22: WARNING - SETFEATURES ENABLE WCACHE taskqueue timeout - completing
request directly

ad22: WARNING - SET_MULTI taskqueue timeout - completing request directly

ad22: TIMEOUT - READ_DMA retrying (1 retry left) LBA=141145

 

Downgrading to the 200706 snapshot fixed the errors.

 

I found the following after searching a bit on google

And with a bit of trial-and-error I found that the following is the one
causing these errors.

A kernel made before this gives no errors, and a kernel make right after
this gives the errors.

 

Anyone have a clue to what could cause the errors?

Or a hint to what I can do to help fix the error.
