It seems like it doesn't always have time to initialize the firmware. I
tried disabling all power-saving features in the BIOS, but the problem
still occurs occasionally.

I also found a dmesg log from another user with a Lenovo ThinkPad X1
Carbon Gen13 with the same error.

So this isn't the only issue.

Is there a way to increase some timeouts or force the firmware to load?
