Hi *, for a long time I got messages like i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun i915 0000:00:02.0: [drm] *ERROR* Atomic update failure on pipe B (start=315366 end=315367) time 312 us, min 1431, max 1439, scanline start 1417, end 1444 from time to time, but this didn't seem to have any further impact on the system. But starting this week about three times a day the machine freezes completely with no apparent reason besides more of the above mentioned messages. No other error messages are shown in the journal or any other logs. This does not happen with Windows 10 running on the same machine, but from an external thunderbolt ssd instead of the internal M.2 ssd. Machine is a Dell Inc. XPS 13 9370/0F6P3V, BIOS 1.13.1 07/08/2020. Does anyone else face this problem? Any idea what to check or do against it? TIA. Bye. Michael.
