I am sorry, but I meant that message only as a notification that it does not 
work. I wanted to be more descriptive in BZ.

However, I'll try to answer to all your questions as good as I can. So. Prior to 
suspend I see the same thing with all three kernels and that is some message 
saying that it suspending consoles. Then the computer suspends. I wake up the 
notebook by pressing a key on a keyboard. During resume I see nothing save for 
hdd LED blinking. The computer starts, at least so it seems, but screen, as well 
as my USB mouse, remains turned off. Disk work for some time and then stops. 
Nothing more happens after that. In /var/log/messages I didn't find anything, no 
kernel panic anywhere. Yep, I am running on LVM and have SELinux turned off. 
According to the bug I have found and added comments to (#241310), it seems that 
it broke between 3176 and 3180 kernels (I'll try both to confirm this as soon as 
I download them). Hope this info helps.

If you still need more info just ask, I will give you all I can.
