Comment 1 Stanislaw Gruszka 2012-01-21 13:24:08 UTC

Looks like another issue caused by "scan optimizations", fixed in patch for bug 771094. Please test kernel-3.2.1-1.fc16 (http://koji.fedoraproject.org/koji/buildinfo?buildID=294396) and let us know.

Comment 2 udtduetl 2012-01-21 14:20:23 UTC

I can't reproduce the bug with that new kernel, seems to fix the problem.

Comment 3 Stanislaw Gruszka 2012-01-24 07:59:30 UTC

kernel-3.2.1-3.fc16 has been pushed to the Fedora 16 stable repository.  If
problems still persist, please make note of it in this bug report.
