Seen with the 7.0-rc7, but probably happens with any other Linux version
as well. Let me know, if I can help resolving this issue.
My first thought when I see "Firmware Bug" is that it's a firmware bug,
not something the kernel can help with.

That machine also has problems with IRQs as the graphics driver never receives any. I tried acpi=noirq and irqpoll without success. Anything else I could try?

Best regards
Thomas
