   I can reproduce this bug on my laptop (Lenovo X200).
The last message before the Call Trace is : "kvm: exiting hardware virtualization ",attached is the screenshot of the panic. If remove the kvm module,then reboot works well.

Suspending KVM hosts is not supported currently.

If suspend/resume support is needed (on a machine that is not a KVM host), the user needs to uninstall kmod-kvm.
Comment 4 Eduardo Habkost 2009-10-15 19:17:08 UTC 
Should be fixed by the fix for bug #510814. Moving to POST to reflect the fix status.
Comment 6 Eduardo Habkost 2009-10-21 19:31:00 UTC 
The fix for bug #510814 (that should solve this bug) is in kernel-2.6.18-170.el5
You can download this test kernel from http://people.redhat.com/dzickus/el5

Testing is welcome.

retest in kernel -185, host is auto-resume due to 550014, but the kernel oops on rebooting is gone.
