Subject: [REGRESSION]: hibernation issues on 3.5.4/3.5.5

Hello.

I am experiencing problems with hibernation (echo disk >
/sys/power/state) on both 3.5.4 and 3.5.5. Note: Problem did not
exist up through 3.5.2 (I skipped 3.5.3).

Upon resume from hibernation, the % loading progress indicator
appears. At some point the image stops loading and the system
reverts to a standard cold-boot sequence.

Logs (attached below) reveal it is erroring out with "Invalid LZO
uncompressed length".

Many thanks for your help.

~ Andy
