Additional info: This started with kernel 3.9.9.x
*NOTE* on above Kernel-3.9.9-301.fc19 should have been Kernel-3.9.9-201.fc18 or greater.
*NOTE* Blacklisting the acpu-cpufreq module is also a workaround for this.
Setting: intel_pstate=disable intel_idle.max_cstate=0 processor.max_cstate=1 Also seems to workaround the issue.
*********** 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.
Recent FC19 kernels do not seem to exhibit the issue. Closing.
