Uninstalling the tlp package resolved this issue for me (Ubuntu 14.04).
Disabling laptop_mode also seemed to help:
echo 0 /proc/sys/vm/laptop_mode

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 0x5 action
0xe
One Additional note, when shifting from high_performance to low_power
modes of operation, no errors are encountered. It only seems to happen
when going from a low to high state.

I am getting this in freshly upgraded Trusty Tahr.
It previsely mirrors the previously reported bug in every respect and I
always get the following kernel disk error when I attempt to resume
after plugging back the power cord in when running on battery power:

I think I see this with Ubuntu saucy (Kernel 3.11.0-12-generic 64 bit.),
on a Thinkpad T520. I see it even when running on external power and
'link_power_management_policy' set to 'max_performance':
