Before that I got the EFI screen and could select a kernel, but the keyboard is not initialised so the system does respond to the cursor keys at all. Kernel: 15.19.6-200.fc36 default selection and obviously installed by update 15.17.5-300.fc36 I guess the kernel install by installation image It follows the message in 1 line Booting ‚Fedora Linux (5.19.6-200.fc36.aarch64) 36 (Server Edition)‘ Displays several seconds, then a screen refresh and just the 4 lines >> Then nothing happened anymore. > > Does it just hang there? Does it eventually drop you to an emergency shell? Just hanging there, no emergency shell, unfortunately. 1 time (out of several tries) I got additional output: 10.951731. Unable zu handle kernel execute from non-executable memory at virtual address (16 x 0) and 27 lines of messages. I was able to take a picture with my phone which I am happy to send you if if helps. > >> One question is, how to fix it. > > Hard tell tell.

For my case here it was a fresh installation, so there is no loss of data (though of course I'd like it up and running so I can use it productively. It runs my server monitoring software). But I think it is urgent to find the cause and fix it, before other users may be severely impaired. > >> The other question is how can such a disaster happen?

Yes, indeed. But we managed for years now to find such issues before we published an update - at least as far as I remember the updates of all our servers. >> Update messages >> >> Updating: selinux-policy-36.14-1.fc36.noarch 240/670 > > You've included a very small part of the update, it shows there's 670 > update transactions happening, you've included a random selection > between 240-248, then 251-255 then to 351-354 and then back to the > 250s.

I selected all item with an „unusual“ message expecting one of those being the culprit. But obviously, it is the kernel. I can attach the m2 board to another machine and try to reconfigure grub to use the old kernel, if that helps.
