Comment 3 for bug 1953671

Per my comments in the issue description, I can't run apport-collect because I can't boot the 5.15 or 5.16 kernels. And when I try to run it for 5.14.21 it tells me I'm running a mainline kernel, despite having installed the debs from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.14.21/.

Please let me know if there is any other information I can usefully provide however.
