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.
