Bug#644174: My system resumes from "suspend to disk" with FLASH disk connected to the USB 3.0 port, and starts with that disks if i915.modest=0 is given

Hi,

I've performed tests suggested by Jonathan in my system.

1st test:

I have started the system, connected the FLASH disk to the USB 3.0 port
and suspended it by "echo disk > /sys/power/state".

Then I pressed the POWER button to switch the system on again, and it 
has resumed!

Similarly, the system resumed after "Hibernate" triggered from the KDE menu.


2nd test:

With "i915.modeset=0" my system started with FLASH disk connected to the 
USB 3.0 port


I attach logs (dmesg) and acpidumps after both tests.
