The hardware: HP Envy4 laptop. Replace "hard drive" with "SSD".
The setup: Dual boot, swap partition for Linux hibernation. Gnome power manager.

The problem:

When I hit suspend in Gnome or suspend to disk after setting up the hibernation partition, it does something weird:

First, the machine seems to suspend. Then seconds later it wakes up and writes a bunch of stuff to disk and then shuts off... this isn't S3! It seems to have gone to S4 hibernate somehow.

When I turn the machine back on, it seems to resume fine from disk.

HOWEVER! I notice that my swap partition is corrupt! When I shut down and restart the machine, the swap partition is no longer recognized as a valid swap partition.

With the swap partition invalid, hibernate no longer works... BUT if I hit "suspend" again, this time it will suspend and not touch the hard drive. The power LED blinks as if it were in S3 suspend-to-RAM, and it resumes just fine.

Anyone know what's going on here? I'm using the kernel default swsusp code but it shouldn't be triggered for the S3 suspend-to-RAM?

My initial guess is that ACPI BIOS is actually trying to suspend to disk and not linux swsusp. I can't think of how or why the swap partition gets corrupted.

Any thoughts on why my swap partition gets eaten?

Are you running a 3.6-rcX kernel? AFAIK they are implementing something like on Windows/OSX, hybrid suspend/hibernate, maybe it's got to do with it.

I'm using 3.4.9 (x86_64 stable?), are they doing in-kernel hybrid suspend in that version?

AFAIK not, it's only scheduled for 3.6 or 3.7.

I'm on 3.5.3 and can't reproduce this, but then again, I'm not using gnome.

I'm pretty sure this is BIOS and not Linux corrupting that partition. Going to try to put swsusp partition somewhere else and see where/if it still corrupts...
Also I wonder if Intel Rapid Start is causing some of this headache...
