Description Joachim Frieben 2016-08-11 04:53:47 UTC 
Description of problem:
Recent kernels of the 4.8.0 development line lead to a kernel panic and system freeze on my Lenovo ThinkPad T400 when shutting down the machine. It is stuck at that point and needs a hard reset. Kernel 4.8.0-0.rc1.git1.1.fc25 was the first one to fix this issue.

Version-Release number of selected component (if applicable):
kernel-4.8.0-0.rc1.git0.1.fc25

How reproducible:
Always

Steps to Reproduce:
1. Shut down or reboot Lenovo ThinkPad T400 running kernel 4.8.0 prior to 4.8.0-0.rc1.git1.1.fc25.

Actual results:
Kernel panic before shut down or reboot procedure are completed.

Expected results:
System shuts down or reboots cleanly.

Additional info:
- issue fixed by kernel-4.8.0-0.rc1.git1.1.fc25.
- issue does not affect a virtual machine running kernel-4.8.0-0.rc1.git0.1.fc25.
Comment 1 Joachim Frieben 2016-08-11 04:57:24 UTC 
According to https://bugzilla.redhat.com/show_bug.cgi?id=1361614#c11, kernel-4.8.0-0.rc1.git0.1.fc25 is scheduled for inclusion into Fedora 25 Alpha which should be avoided.
