[6.12.12] Harddrives can't be spun down

Neither via the interface, nor via hdparm -y can I spin down my harddrives. Works again after downgrade to 6.12.11

root@Mediadinger:~# hdparm -y /dev/sdi

/dev/sdi:
SG_IO: bad/missing sense data, sb[]:  70 00 01 00 00 00 00 0a 00 50 40 ff 00 1d 00 00 00 81 00 00 00 00 00 00 00 00 00 00 00 00 00 00
 drive state is:  unknown

Since my public ipv6 block is all over the place in the diagnostics file, I am hesitant to post it. I'd rather supply information on demand.
