Sorry for the noise. For the record, I validated the equivalent fix on a Panther Lake laptop (Arc B390, 8086:b080, eDP 3120x2080@120): it resolves the boot-time "CPU pipe A FIFO underrun" and the scanout corruption on the first KMS client. Happy to test Ville's series on the same hardware if useful.
