[Touch-packages] [Bug 1777674] Re: Ubuntu 18.04 hangs at "kvm: exiting hardware virtualization" on AMD servers
Update: I was under the assumption that kvm/kvm_amd module was the suspect. But I was wrong. Reason - I tried performing '#modprobe -r kvm_amd kvm' before issuing '#systemctl reboot' in the reboot script and the system still halted with Ubuntu 18.04 kernel. @jsalisbury - I will keep it today and update you by tomorrow. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1777674 Title: Ubuntu 18.04 hangs at "kvm: exiting hardware virtualization" on AMD servers Status in dellserver: New Status in linux package in Ubuntu: Incomplete Status in systemd package in Ubuntu: New Status in linux source package in Bionic: Incomplete Status in systemd source package in Bionic: New Bug description: 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.
