Dear kind Fedora users,

When there was a kernel upgrade from 6.5.12 to 6.6.2, the 6.6.2-fc39 kernel, 
the 6.6.3, and 6.6.4*.fc39 kernel fail to boot. Machine just hangs. It used to 
just work great. Now the machine hangs and I have to install updates and 
exclude the kernels with sudo dnf upgrade --exclude=kernel* .

I have successfully run the 6.6.x Fedora kernels on a raspberry pi 4. So I know 
those kernels work, except on that machine. If I install the new kernels, boot 
hangs indefinitely with no response. I will like to find out how I can check 
what is going on and successfully boot a newer 6.6.x kernels. I can send 
information for machine. It is a Dell XPS 8950 or something like that.

At the boot menu, edit the grub command line and remove the "rghb quiet"
from the end before booting. Then see where it gets stuck.

Upon installing new kernel 6.6.4-200.fc39.x86_64

It stops at last line and it just sits there :(

        Starting systemd-fsck-root.service - File System Check on 
/dev/disk/by-uuid/8ff57a6b-2a55-4e9d-870d-855d-855d68d35bee...
[ OK ] Starting systemd-fsck-root.service - File System Check on 
/dev/disk/by-uuid/8ff57a6b-2a55-4e9d-870d-855d-855d68d35bee.

I have to reboot and select older kernel 6.5.12-*fc39.x86_64

Best Regards & Thank you for trying to help

My guess (and that's all it is) is that something in /etc/fstab can't be mounted after the root filesystem. I'd try adding "noauto" to everything there except for "/," "/home," etc. Just mount the stuff you must have to get the system up. Also, maybe (???) set the last arg on the fstab lines to 0 rather than 1 or 2. Everyone on the list -- please comment on the last idea. I tried it on a cloud server and it didn't cause a problem, but better to have the experts here weigh in.

* make a copy of fstab

* make the edits to fstab

* test by booting to the 6.5.?? kernel to be sure that still works

* try a 6.6.?? kernel and see what happens
