I have tried the second suggestion: At first this made no difference.
The kernel-latest (5.13) was still rebooting itself.
I took me a while to figure out that additionally I had to recreate
the initramfs belonging to this kernel using the following commands::
sudo mkinitrd new_initramfs-5.13.6-1.fc25.qubes.x86_64.img \
5.13.6-1.fc25.qubes.x86_64
sudo mv initramfs-5.13.6-1.fc25.qubes.x86_64.img \
initramfs-5.13.6-1.fc25.qubes.x86_64.img.orig
sudo mv new_initramfs-5.13.6-1.fc25.qubes.x86_64.img \
initramfs-5.13.6-1.fc25.qubes.x86_64.img
Afterwards I was able to boot into the new kernel. However now I had
to use the builtin keyboard of my laptop to enter the LUKS-Passphrase.
After startup of the sys-usb qube the external keyboard becomes usable
again.
Furthermore me and also some others in our german language Qubes-OS
user group noticed a new effect: After typing Enter in the LUKS passphrase
input field for some fractions of a second some blinking pixel gibberish
appears above the passphrase input field just before the screen
is cleared.
Neither of these problems were/are present in the stable kernel
vmlinuz-5.4.143-1.fc25.qubes.x86_64 I installed August 27th this year.
So I think those effects could be considered as regressions.
Best regards, Peter Funk
