Description: Ubuntu 18.04 LTS
Release: 18.04
I've installed all the latest updates in my KVM/QEMU VM. After doing so I can boot the 4.15.0-23-generic kernel just fine. When I try to boot the -24 kernel my system hangs. Once I try to boot the -24 kernel, I can no longer go back and boot the -23 kernel. It hangs as well. I reverted to an older QeMU snapshot and then I can boot the -23 kernel. Repeated again, and once I attempt to boot the -24 kernel, can no longer boot older kernels, so it appears that it is changing or damaging something on my system.
Hang looks like this. If I boot with quiet,splash and hit escape, I get an error:
A start job is running for Hold until boot process finishes up (20s / no limit)
If I remove quiet,splash option, I just get the following and the system is hung, never gives login prompt:
[ OK ] Started Tool to automatically coolect and submit kernel crash signatures
[ OK ] Started User Manager for UID 120.
Note, I have installed the 4.15.0-24-generic kernel directly on my host system (Dell XPS 9360), and I don't have any problems with it there.
