I started a kernel bisect between v4.14 final and v4.15-rc1. The kernel bisect will require testing of about 7-10 test kernels. I built the first test kernel, up to the following commit: 1be2172e96e33bfa22a5c7a651f768ef30ce3984 The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1777674 Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

Ideally, we'd want to bisect and fix the kernel itself to reliably shutdown. yanking ahci sounds like a large hammer.

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 Kernel Packages, which is subscribed to linux 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.
