Comment 84 for bug 539467

This issue appears to be present again on kernsl 3.13 (all) 3.16 (all) and 3.17 (all)

upon shifting sata link power from min_power state to max_performance state all kernels report various forms of this error:

[ 45.200582] ata3.00: exception Emask 0x10 SAct 0x8000 SErr 0x50000 action 0xe frozen

With the current 3.13 kernel reporting the most severe errors of block write failures, etc.

The machine this is being tested on is an A05 bios Dell XPS13 (9333)

As this machine is brand new, it's possible that the HW is actually failing, however SMART doesn't indicate any problems with the block device
