Public bug reported:
Ubuntu 18.04 hangs at "kvm: exiting hardware virtualization" on AMD
servers when under graceful reboot stress for 12hrs.
* This hand is observed only when Onboard SATA DVD Drive is connected.
* Not seen with Ubuntu 16.04.4 (HWE kernel v4.13)
* Seen with Ubuntu 18.04 (4.15.0-23-generic, 4.15.0-20-generic)
Steps:
Setup a DellEMC AMD server with Onboard DVD Drive, install Ubuntu 18.04 and
start reboot stress
After a few reboots, observe that the machine hangs at "kvm: exiting hardware
virtualization" and does not proceed with reboot cycles.
Only physical reset helps in continuing the reboot test.
