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 reboot 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."

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).

I will have these laptops for some time but won't be able to test much beyond a week or two.
