I tried to roll back to right before the above mentioned change
Karsten (well, I assume it was him :-) ) noted on IRC that it might be
the cause of the problems since I have a similar controller, though
not exactly the same one, but it didn't fix the timeouts for me.

For this server I have 3 disks in a graid3 (so no ZFS but the errors
are similar to what I have seen / heard about wrt. ZFS + ata use) and
I get timeouts several times a day which causes FreeBSD to loose
contact with one or more disks where I have to reboot before things
recover (usually FreeBSD panic's enough so the system reboots by
itself).
