--- Comment #2 from Urs Fleisch <urs_fleisch at yahoo.de> ---
I could not do a kernel bisect because I have the regression only on Ubuntu. I
have now switched to Arch Linux where I still have the same (not optimal but at
least usable) behavior: After having suspended to disk, I am able to suspend to
RAM. After a reboot or shutdown, it does not work.

I do not know if the Ubuntu kernel is "patched" to cause the failure or if the
way how to hibernate (on Arch Linux, I have to used the
resume=/dev/swap-partition-name parameter whereas on Ubuntu no additional
kernel parameter seems to be necessary) has an effect. I also wonder what
effect from hibernation is "healing" suspend to RAM.
