Bug Description
Sometimes on reboots and quick cold boots (poweroff then hit power immediately) I get
```
error: Command failed. -repeated a number of times then
error: you need to load the kernel first.
Press any key to continue...
```
* cold booting usually fixes this and I'm able to boot normally.
* I have three identical laptops and have seen the issue on 2 (i've only installed 20.04 on two).
* I don't see the problem on 18.04.
* If I go into the grub> menu many commands fail "true" "cat" but some don't "ls" "false."
* Once i'm in grub> menu I can fix things by running "rmmod tpm" then subsequent commands start working again and I can exit and continue.
The source for grub points to tpm.c when I search for "Command failed." I also notice that there's no such file in 2.02 version of grub so maybe that's related to why it doesn't work.
I haven't been able to find a combination of BIOS settings that mitigates this. I have tried disabling everything I could think of.
This laptop has Intel PTT which I think is baked into the BIOS (which I upgraded to the newest).
WORKAROUND 1:
* Once the system fails to boot:
* enter grub> by pressing 'c'
* type 'rmmod tmp'
* press 'esc' to go back to menu and select desired option and system boots again.
WORKAROUND 2:
sudo cp /etc/grub.
sudo bash -c 'echo "rmmod tpm" >> /etc/grub.
sudo update-grub
I will have these laptops for some time but won't be able to test much beyond a week or two most likely.

Upon some further research, it looks like this bug is similar: https:/ /bugs.launchpad .net/ubuntu/ +source/ grub2/+ bug/1848892
However, that bug seems to happen all the time where as for me it's intermittent.
I tried the workaround from the linked bug and can confirm that when I experience the issue I can boot successfully by:
* 'c'
* grub> rmmod tpm
* 'esc'
* 'enter' to select normal boot menu entry.
