Yes! I'm able to reproduce it 90%! We can exclude X, 80211 and so ath5k too (I removed them from /lib/modules, so they won't ever load). I set the water mark at 1700 megabytes to allocate by the testing programs, so that it eats almost all free available memory. Then, I wait to "alloced 1" and then pm-suspend on second console. After resume, it spits out the corruption. I'm going to bisect it, will be back in few hours ;).
