*** Bug 198036 has been marked as a duplicate of this bug. *** should be fixed in tomorrows rawhide push (kernel-2.6.17-1.2375.fc6 or higher). Upgraded to current rawhide (2.6.17-2439.fc6 smp) still happening. I no longer see this message with the newer kernels (tested with 2.6.17-1.2462.fc6). Can be closed? |
