Created attachment 1666750 [details] Kernel log from failed boot 1. Please describe the problem: After a dnf upgrade just now, Fedora 31 fails to boot with the latest released kernel because of a hang at "Starting Cryptography Setup". Choosing the previous installed kernel in the GRUB menu at boot resulted in a successful boot. 2. What is the Version-Release number of the kernel: 5.5.6-201 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : Worked under all kernels used through 5.4.19-200 (the kernel I'm currently booted into). 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: The boot failure is every time on this system, but I haven't yet tried to induce a failure on a new system. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: Unknown -- this is a work laptop so would rather not try a Rawhide kernel on it. 6. Are you running any modules that not shipped with directly Fedora's kernel?: No 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag.
This is a known issue on devices which use the new sof-hda audio driver because they have digital mics. This has been fixed in 5.5.7, which is in updates-testing now. The following should work to update your kernel to 5.5.7: sudo dnf --enablerepo=updates-testing update 'kernel*' *** This bug has been marked as a duplicate of bug 1808784 ***
