>Description:
I installed smartmontools package (ver: 5.32), from ports. It compiled without any errors as is remember. When I try to get smart data from my disk, i get the following:

smartctl -a /dev/da1

Of course this worked before with the same disk, but not with the same scsi card. I used the integrated AHA-7880 UW, now the PCI AHA-2940U2W (7980). The card and disk is working perfectly. I tried both the LVD and SE channel, the result is the same.

I don't really whether it's a kernel driver problem or a sw bug in smartmontool or maybe both.

relevant dmesg:

 I hoped it helped, of course I can post any further information/data if needed.
