Comment 1 Josh Boyer 2011-09-26 17:48:10 UTC

Have you seen this with the latest 2.6.40 kernel in F15?

Comment 2 mhaitham 2011-09-26 17:56:59 UTC

Yes sir, I tried it with the kernel 2.6.40 installed but still crashed after multiple (3-5) suspend-resume cycles.

Not just Fedora 15 had this problem, most other distros did as well, including: Arch Linux, Kororaa, Developmental OpenSuse, Mandriva 2011. Those that did not, included Pardus, Sabayon and Debian Stable (which I switched to so as to have a functioning system).

Comment 3 Dave Jones 2012-04-11 16:25:48 UTC

try the 2.6.43.1 update. That has a memory corruption bug fix that may explain this.
