Created attachment 872021 [details]
grep kernel: /var/log/messages

Shortly after booting I start to see "soft lockup" messages appear on terminals, and shortly after that the system becomes unresponsive.  See attached log output for the full messages.

This is new since I updated to kernel-PAE-3.13.5-101.fc19.i686.

Note that the captured log is when I was using the NVidia graphics drivers, but I saw (what appeared to be) the same problem with nouveau; in this case the system became unresponsive so quickly that syslog was not written.

This crash does not happen if I do not start the kvm VM.

*********** 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 19 kernel bugs.

Fedora 19 has now been rebased to 3.13.5-100.fc19.  Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.
