Yeap, the SG command is fine. The drive is being weird tho. The allocation length field says 10 bytes, so it should just have transferred 10 bytes without causing HSM violation. Can you please apply the attached patch and report what the kernel says after triggering the error condition?
Thanks for looking at this, the kernel now says: <4>ata2.00: HSM violation: eh_analyze_tf: BUSY|DRQ <3>ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen<3>ata2.00: cmd a0/00:00:00:0a:00/00:00:00:00:00/a0 tag 0 cdb 0x5a data 10 in <4> res 58/00:02:00:0a:00/00:00:00:00:00/a0 Emask 0x2 (HSM violation)
