This also happens with the kernel in xubuntu-22.04-beta-desktop- amd64.iso, so it will block me upgrading that machine to Jammy when it's released. Is there anything I can do to help? I'm not familiar with debugging kernel drivers, but I'm a competent general developer, and I'm prepared to put in

Public bug reported: I'm running Ubuntu 20.04 with HWE kernels. The 5.11 kernel stream has been working fine for me (and supported the network device on my reasonably recent PC, which 20.04's default kernel didn't). But the 5.13 and 5.14 kernels all hang on boot. If I edit the GRUB boot commands
