Hi all,
I updated a Dell XPS laptop from CentOS 8.1 (1911) to 8.2 (2004).
Installed kernels are
kernel-4.18.0-147.5.1.el8_1.x86_64
kernel-4.18.0-147.8.1.el8_1.x86_64
kernel-4.18.0-193.6.3.el8_2.x86_64
Unfortunately I can not boot into the latest
kernel-4.18.0-193.6.3.el8_2.x86_64.
After grub2 screen I only see following line:
EFI stub: UEFI Secure Boot is enabled
Booting into the older kernel is still possible. The
above line appears and after that the normal kernel
output scrolls over the screen (rhgb quiet disabled).
Is the new kernel correctly signed?
What can I do?

Hi Leon,
Don't think that it's due to secureboot, as on my work laptop (thinkpad
t490s), I have secureboot on, and kernel working fine.
OTOH, on my family laptop (also in secureboot mode), when I updated from
8.1.1011 to 8.2.2004, laptop became unresponsive during the
microcode_ctl update (in scriptlet) and after that it auto-reset itself
, so in the middle of the whole rpm transaction.
I tried to recover it but it was to a point where it was faster to just
reinstall from scratch with 8.2.2004, which I did ... and in gnome,
everything was fine, etc (adding repo, pkgs) but then on the *same*
kernel it was installed with, just tried a reboot, and nothing : grub
shows menu, you select kernel and on upper left there is only cursor
(fixed) and nothing happens ..
I'll try to diagnose what's the issue as actually that means troubles
with family using that laptop :)
Did you got managed to boot kernel-4.18.0-193.14.2.el8_2 or a newer one?
I must still boot into kernel-4.18.0-147.8.1.el8_1.x86_64 ... and with
the upcoming new kernel that depends on a new shim and grub2 package I
wonder about the implications for my XPS hardware ...
JFYI: latest (kernel-4.18.0-227.el8.x86_64) 8-stream kernel is
bootable on this machine ... (full updated (C8.2.2004) with latest
shim, grub2 stuff. Just the kernel is from 8-stream) ...
