[Bug 50031] Re: [regression] Suspend [to-RAM and to-disk] is broken in 2.6.15-25.43

[DaveAbrahams]

Amendment:

The problem with suspend to disk appears to be that it hoses my LVM2
swap partition and at boot I see

  kernel: Unable to find swap-space signature

The swap partition is unusable until I run mkswap on it again.  Another
possible explanation is that suspend is *supposed* to essentially
reformat my swap, and since the resume functionality is not able to
recognize it, the partition remains in a format that's unusable for swap
space.  Anyway, this is speculation; someone who knows swsusp would be
able to handle this better than I.

That said, now suspend-to/resume-from RAM are working for me. Per
https://launchpad.net/distros/ubuntu/+source/thinkpad/+bug/50324/comments/6,
I needed the following options in /etc/default/acpi-support:

  ACPI_SLEEP=true
  MODULES="fglrx" # unload/reload fglrx module when suspending

I do *not* have SAVE_VBA_STATE=true uncommented.
