I get the same issue on LSI SAS2008 using the mpt2sas driver in 2.6.32-rc5.  
It wouldn't be a big deal, but it actually increments
/sys/block/$dev/device/ioerr_cnt, which I'd like to use for quick & dirty
checks for drives going south (I realize it's not perfect).

This occurs with both smartmontools 5.38-2+lenny1 as shipped with Debian 5 and
with a local backport of 5.38+svn2956 from experimental.

Trying smartctl -d scsi returns an outright failure. 

I can also reproduce with sg_sat_identify -c.

~$ sudo sg_sat_identify -c /dev/sg13
~$ dmesg |tail -n 5
