Description Brian Monroe 2015-04-28 04:13:59 UTC

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

http://fpaste.org/218248/43075468/ - dmesg --kernel output after shutting down and getting reboot action instead.

Comment 4 Brian Monroe 2015-05-14 22:19:29 UTC

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.
