Bug 1900233 - Grub fails to boot with tpm.c errors

Hi all,

Apologies if I'm doing this wrong but I've never had to contact you before.
There is a bug that was logged on RedHat Bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=1900233

Which a user and myself both have the same issue. I'm running a Lenovo C940
and if I recall he has a C740.
The poster thepiguy did a fair bit of back and forth with the Fedora team
to identify where and how this was happening but deemed it not a Fedora
specific issue as with the right conditions the same issue was present in
Arch.

I wanted to bring this to your attention as I'd like to help solve this
issue if possible as it's a very annoying issue and I don't want to disable
my TPM to work around it (As some have suggested on another post in the
Fedora forum)
https://ask.fedoraproject.org/t/grub-core-error-you-need-to-load-the-kernel-first/14405

Again apologies if I've raised this with you incorrectly and please let me
know if there's anything I can do to assist.

Kind regards,
Bruno

Hi! Thank you so much for getting back to me so quickly. I'd be more than
happy to try the patch out, unfortunately I'm not familiar with how to
apply it. Would you have instruction for me to follow?

I see + & - element so I'm guessing I'm to remove/replace these lines in a
file but I see Git commands so am I supposed to download a Git repo and
modify the files and then compile?

I'm a long time Linux user but only recently started to learn about Git and
manual installs. I'm happy to learn and be more helpful in the community
but if you could point me in the right direction to understand the how to
do this I'd appreciate it 😅😄.

Apologies for my lack of knowledge.

Kind regards,
Bruno

Yep, git is your friend. The most important commands for you are "git clone"
and "git am". When you have updated GRUB source please take a look at INSTALL
file. It contains instructions how to build and install the GRUB from source.
