Created attachment 693958 [details] dmesg The only problem I noticed was that my Wi-Fi went down. I should note that this all occurred at a Wi-Fi spoofing awareness event, so there may have been multiple available access points broadcasting the same SSID. abrt reports about eight similar kernel bugs after this one, but they're all "tainted" (flags: GW) and I'm instructed not to report them.
Démarrage de la session Package: kernel Architecture: i686 OS Release: Fedora release 18 (Spherical Cow)
I was not aware of an issue until I saw the ABRT message.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 18 kernel bugs. Fedora 18 has now been rebased to 3.11.4-101.fc18. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 19, and are still experiencing this issue, please change the version to Fedora 19. If you experience different issues, please open a new bug report for those.
I have not seen this bug since February.
