I have a problem booting my fedora 36 (in version 35 the same thing happens to me and I have tried to reinstall from 0 with the same result). When I boot the grub I get this error.
error ..... tpm.c:148:Unknown TPM error
Searching the internet I have found a solution (I think the only one for now) which is to add in the grub entry this line just in front of the first insmod
rmmod tpm
This works fine for that boot but the change is not persistent and the next time I boot I have to repeat the process again.
I have found the template file that is used in the grub.cfg generation and I have found the line where it does the insmod that I left behind in the rmmod startup. The file is 10_linux in /etc/grub.d and I added this.
echo " rmmod tpm" | sed "s/^/$submenu_indentation/"
echo " insmod gzio" | sed "s/^/$submenu_indentation/"
and then I recreated the configuration file with
# grub2-mkconfig -o /boot/grub2/grub.cfg
and although I see that it uses that template file when generating the cfg it does not include the rmmod.
My question would be where do I have to put that line to make the change persistent between reboots.
I would also like to know if there is a definitive solution to this problem.
Regards
