The firmware error at boot.
Happens on the Surface Pro 3, could be related to iwifi, the Intel integrated
graphics, thermals, RAM, or even possibly the SSD? I have noticed the message
display at boot since about Kernel 5.12.7 (but not before) and the system boots
seemingly normally anyway, at least at first glance.
Also, I don’t know if this has any relevance really, but it seems that together
with the mentioned issue, I also get errors about Intel PowerClamp mentioned
next to the ACPI error.
Thanks to all, for any guidance on this in advance.
