Hello,

After upgrade to 3.5.x kernel, suspend stop to work. Looking on dmesg, I obtain this kernel OPS:

I tested 3.6/3.7-rc kernel but problem persist. 
The problem does not seem to be related to a specific distribution, as can be seen at the following link:
Ubuntu 12.10: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1069707/comments/35
Fedora 16:https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1069707/comments/38

Thanks in advance for support.
