That RedHat bugzilla is from kernel-3.9.0-0.rc4.git0.1.fc19.x86_64. Does that kernel include Matthew's patch from Mar 19? I'm wondering if that report is for the same problem Mantas saw and possibly would be *fixed* by the Mar 19 patch, or if it is for a problem with the Mar 19 patch itself. I would check this myself, but I don't know how to figure out what's in kernel-3.9.0-0.rc4.git0.1.fc19.x86_64. Mantas confirmed that the Mar 19 problem fixed *his* issue, but I haven't seen any reports from either Mantas or Chris (the RedHat bugzilla reporter) for the new Mar 26 patches. > Sigh.
