We see that that vmlinuz-5.4.0-166-generic was deplyed as an automatic update a few hours ago, hopefully this resolves the problem :)

About 1/1000 boots of qemu results in a failed boot hanging at 100% CPU indefinately. A number of our utilities are using qemu for processing, so we get a lot of processes spinning at 100% that we need to clean up regularly. Ubuntu: 20.04 Linux: 5.4.0-164.181 Qemu: 4.2-3ubuntu6.27 This problem was not seen before the release of Linux. 5.4.0-164.181 on sept. 1. What you expected to happen: Qemu boots linux reliably. What happened instead: Qemu hangs at 100% indefinately. --- ProblemType: Bug AlsaVersion: Advanced Linux Sound Architecture Driver Version k5.4.0-164-generic.
