Could you please download and install https://launchpad.net/ubuntu/+source/finalrd/3/+build/15227702/+files/finalrd_3_all.deb
(this is a link from https://launchpad.net/ubuntu/+source/finalrd/3/+build/15227702 ) And check if that helps with reboots? This should perform pivot-root from rootfs to initramfs, and generally improve shutdown reliability. However, I do suspect this to be a kernel issue. If ahci is really identified as a kernel shutdown culprit, we might want to ship an executable script in /lib/systemd/system-shutdown/yank-modules.sh or somesuch which would rmmod ahci if possible. So far I do not have any indications that it is indeed systemd holding up reboot, and not the kernel. -- 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 with DVD Status in dellserver: New Status in linux package in Ubuntu: Incomplete Status in systemd package in Ubuntu: Incomplete Status in linux source package in Bionic: Incomplete 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.
