wow, haven't seen that warning in a while. Eric ? Another one that triggers this: while true; do rmmod coretemp; modprobe coretemp; done Albert, that's a different trace. I just reported it upstream. [mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update.

[mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update. I haven't seen any other report of this, so I'm calling it fixed. Reopen if it's still a problem with -debug/rawhide. |
