Hi,
There seems to be a problem on my Acer box which is related to DIPM
and switching the power source. Namely, when I detach the AC adapter from
the machine, the disk (which is an Intel SSD) freezes for a while and
something like this appears in dmesg:
[ 2177.808120] ata1.00: exception Emask 0x0 SAct 0x7 SErr 0xd0002 action 0x6 frozen

Then, when the AC adapter is attached again, the SSD freezes again and this
appears in dmesg:
[178523.064145] ata1.00: qc timeout (cmd 0xef)
[178523.064228] ata1.00: failed to disable DIPM, Emask 0x4

[178523.572051] ata1: EH complete
That seems to be reproducible 100% of the time. Moreover, if the box is
suspended on AC power and then resume on battery power, something more serious
happens:

This doesn't happen if the box is both suspended and resumed on battery
power.
I have verified that the issue described above doesn't happen with
the appended patch applied.
The hardware is:
