Description Trever Adams 2016-03-16 22:33:18 UTC 
Description of problem:
System locks up in one of two places (shortly after kvm start or disable due to bios and just as gdm is showing the mouse cursor but nothing else). I believe this is kernel because 4.3.x and 4.4.x from Fedora 23 do not show this even after upgrade to Fedora 24. 4.5.0 rc3 and final both show it.

This is on an HP laptop. I will provide more information on the laptop when I am near enough to get the model number and if I can get it to boot so I can get lspci, etc.

This appears to have been fixed in 4.5.4 (maybe the double-free issue mentioned for amdgpus). I will wait a few days before confirming this is fixed.
