Comment 2 John W. Linville 2010-06-02 15:03:07 UTC
Test kernels w/ above patch building here:


Give them a try?  Can you replicate the problem with those kernels?

Comment 3 Mihai Harpau 2010-06-02 15:30:34 UTC
I will try and report what are the results.

Comment 4 John W. Linville 2010-06-09 18:07:50 UTC
Ping?  Koji won't keep those test kernels forever...

Comment 5 Mihai Harpau 2010-06-13 08:45:54 UTC
After more suspend/resume cycles I can confirm that kernel from http://koji.fedoraproject.org/koji/taskinfo?taskID=2225224 fixed this bug.
