The solaris specific code was not changed between 5.39 and 5.40. The 
commands 0x85 and 0xa1 are the 16 and 12 byte versions of SAT ATA 
PASS-THROUGH 16 and 12 which are used to for all ATA commands if '-d 
sat' is specified.

"smartctl -a" is equivalent to "smartctl -H -i -c -A -l error -l 
selftest -l selective". Please try which of those options produce a 
kernel warning.
