On Linux 2.6.33, wich includes aacraid version 24702 (that's at least what
Adaptec's arcconf tells me), we're unable to query the smart information (SATA
disks attached to an Adaptec 52445):

On 2.6.32, we can use the aacraid driver from adaptec (version 24900) and
smartmontools work as expected, but with 2.6.33 their version doesn't compile
anymore.
We really don't want to run their 'enterprise' storage manager software on our
servers to warn us about bad blocks, but as long as we're unable to use
smartctl for this we're quite out of luck :/
So in lk 2.6.32 aacraid driver version 24900 was used
successfully but with lk 2.6.33 the aacraid driver
version reverted to 24702 and didn't work. It might be
interesting to find the aacraid changelog between those
two versions.
Anyway the kernel messages shown by dmesg are just
noise and should disappear in lk 2.6.34 .
IOW "ATA pass through information available" indicates
normal operation of SAT.
smartctl will provide more debug information if a
'-r ioctl,3' option is added.
