After kernel upgrade to 5.8.0.55 my system would no longer boot.

[Keith Jackson]

I have generic Ubuntu kernels 5.8.0.53 and 5.8.0.58 on my system.

After starting up following the latest update my system would not boot. Managed to get back in via Grub manually loading the earlier kernel.

I'm running a custom Quiet PC system with SSD primary drive and data HDDs.

I'm a bit of a noob here but happy to track down any desired logs etc. if possible.

Apologies - It was 5.8.0.55 (Not 5.8.0.58) that's recently been installed - sorry working from memory!

I can't seem to edit the title...

Keith,

I was able to correct the title to 5.8.0-55. We're looking into the issue per https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.8/+bug/1930976 and I am marking this a duplicate of that bug.
