The firmware still seems to crash quicker than previously, but that's a
unrelated problem.

Hello! Do you have some more details (or links) about mentioned firmware crash?

Sure, firmware crashes have always been a problem on the Surface devices. They seem to be related, at least for some of the crashes, to power management. For this reason I disabled powersaving in NetworkManager which used to make it at least stable enough for me, in 5.13 this trick does not seem to work.

The dmesg log attached shows a firmware crash happening, the card does not work even after a reset or remove & rescan on the pci(e) bus.

There are patches [1] which have not been submitted yet and where developed as part of the linux-surface effort [2]. From my experience these patches resolve most if not all of the firmware crashes.

Regards,
Dave Olsthoorn
