I see only one line:

ata0: <ATA channel> at channel 0 on atapci0

ata does not appear anywhere else.

Amazingly (for me) I can't!

Twice I got a panic. The third time,
and thereafter, I get the same error as with GENERIC:

 Mounting from ufs:/dev/ad4s1a failed with error 19.

I also see:

ata0: stat0=0x00 err=0x01 lsb=0x14 msb=0exb
ata0: stat1=0x00 err=0x00 lsb=0x00 msb=0x00
ata0: reset tp2 stat0=00 stat1=00 devices=0x10000

Thanks
