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.
