This is what the kernel output looks like at those times: mt7921e 0000:62:00.0: driver own failed kernel: mt7921e 0000:62:00.0: Timeout for driver own kernel: mt7921e 0000:62:00.0: driver own failed kernel: mt7921e 0000:62:00.0: Timeout for driver own kernel: mt7921e 0000:62:00.0: driver own failed kernel: mt7921e 0000:62:00.0: Timeout for driver own kernel: mt7921e 0000:62:00.0: driver own failed kernel: mt7921e 0000:62:00.0: chip reset failed kernel: mt7921e 0000:62:00.0: Timeout for driver own kernel: Console: switching to colour frame buffer device 360x112 kernel: fbcon: Taking over console kernel: mt7921e 0000:62:00.0: Message 00020001 (seq 1) timeout I have observed the issue on many untainted kernels, and I have had it happen on vanilla kernels not provided by my distro as well. Mine and some other people's reports are available at [1]. More logs of the issue on my system are in the attachments of my original report on the Red Hat Bugzilla [2]. In the past, the issue was reported at [3], which resulted in a patch [4] that only keeps the system running instead of panicking. This means the driver still causes system hangs. I still don't know the root cause of the issue and I would like to get to the bottom of this; any help or guidance is appreciated. Crucially, I have not found a way to reproduce the issue at will. Best regards.
