Subject: Memory corruption during hibernation since 2.6.31
Date: Wednesday, July 28, 2010 - 2:20 pm

Hello,
after very long bisection, I finally found what's causing memory corruption 
during hibernation on my machine sice 2.6.31:
https://bugzilla.kernel.org/show_bug.cgi?id=15753

It's commit c9e444103b5e7a5a3519f9913f59767f92e33baf (mm: reuse unused swap 
entry if necessary).

I don't know anything about swapping in Linux so I don't have a clue what's
wrong with that commit.
