Comment # 11 on bug 913105 from Mark Scott

Hi Takashi

Yes it does go BOOM but the graphics does come up with about half a line and
then freezes, the entire system locks hard and only a physical power reset will
do. I'm of the opinion best candidate causing the issue is to do with the fact
that APM is not supported by these two drives and this scenario used to be
handled by K3.11 however a commit beyond this kernel has caused a regression,
unfortunately I have no other drives that do not support APM to test this
theory. All other drives I have tested (about 6 in total including other WD) do
support APM and cause no problem when resuming from ram. 

I did find a thread over at Arch linux into odd APM behaviour regarding WD
drives that may be semi-relevent.

Just for info:

# smartctl -x /dev/sda | grep APM
APM feature is:   Unavailable
