Description of problem: When asking for a shutdown, the laptop is rebooting Version-Release number of selected component (if applicable): kernel 3.17.4-300.fc21.x86_64 or later. hardware : HP EliteBook 9480m How reproducible: Shutdown the computer Actual results: Reboot Expected results: Stay shutdown Additional info: After additional troubleshooting we noticed that the issue is likely related to the xHCI chipset. Disabling xHCI support in the BIOS and by extension usb3 support, can be used as a work around to resolve the issue. A Fedora bug was filed, but I wanted to report it upstream since it hasn't been resolved yet. It can be viewed here: https://bugzilla.redhat.com/show_bug.cgi?id=1168557

From the list, it was requested to build a kernel with xhci as a module to see if a kernel panic was happening during shutdown. I did this and tried to remove it and re-add (rmmod and modprobe) it to see if a kernel panic happens, but it doesn't.
