Created attachment 298029 [details] 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.
