3.2-git - freeze during hibernation

3.2-git - freeze during hibernation

[Mantas]

Using uswsusp git-17789a0 and Linux git-v3.2-6540-g4c4d285, suspend to
disk freezes right before writing the memory to disk -- "Saving X image
data pages" appears, but the percentage does not, nor is there any disk
activity; all I can do is reboot using Alt+SysRq.

Same version of uswsusp, both suspend to memory and disk, worked
perfectly with Linux v3.2 release and earlier versions. The device is
ASUS K52JT. Any hints?

It does fix this particular issue; the suspend image is written correctly.

However, now it hangs at the "Suspending consoles" message -- sometimes
before writing image, sometimes after...

I will try the same patch against latest linux-git and see if there are
any changes.

Also tested linux git-v3.3-rc1 (currently latest); hibernation now works
fine with the patch posted.
