It's the "-H" that causes the grief.

Thanks,

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.
