I have ZFS raidz1 pool on 6 disks distributed between 4 SATA channels on 
onboard MCP and 2 internal SATA channels of SATA300 TX4 on my test machine; 
before I had constant errors on ad12 and ad16 (machine is not under load, so 
no harm to actual data).


After you patch ad12 and ad16 have been recognized, but it seems driver 
changes some offsets, as there are no ad{12,16}a partitions anymore, and 
fdisk -s ad12 gives me

fdisk: invalid partition table found

while before it produced something like

/dev/ad4: 486344 cyl 16 hd 63 sec
Part        Start        Size Type Flags
   4:           0       50000 0xa5 0x80
