[Bug 539467] Re: SATA link power management causes disk errors and corruption
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:

With the current 3.13 kernel reporting the most severe errors of block

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

Bug description:
SRU Justification for pm-utils-powersave-policy:
Impact: On certain hardware, enabling power saving for the SATA link
can cause data corruption.
How Addressed: The proposed branch removes the sata link power policy
script. This will cause the link to be maintained at the normal power
usage instead of dropping when the power is removed from the machine.
Reproduction: On an affected machine, unplug and plug in the power a
few times. Data corruption will result.
Regression Potential: Removing the script will cause the SATA link to
stay fully powered at all times. This may cause an increase in the
battery usage for some machines. There should be no functionality
regressions or bugs introduced by this change.

Using Lucid on my laptop, I see errors like this in dmesg quite
frequently (every few hours):

Every couple of days, this results in data corruption and my
filesystem being remounted read-only:
[ 6148.305806] Aborting journal on device sda1-8.
[ 6148.325011] EXT4-fs error (device sda1): ext4_journal_start_sb: Detected aborted journal
[ 6148.325018] EXT4-fs (sda1): Remounting filesystem read-only
[ 6148.326702] journal commit I/O error
[ 6148.330975] EXT4-fs error (device sda1) in ext4_reserve_inode_write: Journal has aborted
[ 6148.462572] __ratelimit: 15 callbacks suppressed
Those messages generally appear at the end of dmesg after the event,
just after the "hard resetting link" message. I then have to boot a
live CD and manually run fsck, as I can no longer boot the laptop.
This is happening every couple of days generally, although it happened
3 times in one day last Thursday.
I did contemplate it being a hardware issue, but I tried running the
kernel from Karmic for a couple of days, and that worked ok without a
single error message
