found this after my odyssey with my N36L ahci/zfs-mirror .
Not exactly the same issue but similar a ahci failure.

With ahci loaded "dbench 1000" or copy a 20G file ends with timeouts on
ahcich0 and ahcich1 and a complete unresponsive system. No way to
recover. Only rebooting helps. There is no damage seen on zfs. But
anyway it's not really usable for production. Now running ata again...
