Description poma 2015-11-11 17:42:11 UTC

Description of problem:
Perpetual reboot

Version-Release number of selected component (if applicable):
kernel-core-4.4.0-0.rc0.git4.2.fc24.i686
kernel-core-4.4.0-0.rc0.git5.1.fc24.i686

How reproducible:
101%

Steps to Reproduce:
1. Install 4.4.x kernel
2. Re/boot with 4.4.x kernel

Actual results:
Broken re/boot

Expected results:
Correct re/boot

Additional info:
The machine auto reboots very early,
the last message observed on the display before the actual auto reboot:
"agpgart: Detected ..."

HW:
CPU op-mode(s):        32-bit
Vendor ID:             AuthenticAMD

Tested also:
4.4.0-0.rc0.git2.1.fc24
4.4.0-0.rc0.git9.1.fc24

In the virtual machine, boot stops at the
[    0.000000] random: nonblocking pool is initialized

and there remains - no auto reboot as on baremetal.
