Hi!

When 5.4-rc1 is booted on thinkpad X220 I get "snow" and other
artefacts on digital output.

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation
Core Processor Family Integrated Graphics Controller (rev 09)

It already snows when kernel is booting, snow continues in X.

HDMI1 connected primary 1920x1080+0+0 (normal left inverted right x
axis y axis) 478mm x 268mm
   1920x1080     60.00*+


Snow continues in other video modes:

pavel@duo:~$  xrandr --output HDMI1 --mode 1024x768
pavel@duo:~$

VGA output appears normal.

Any ideas?

Best regards,
									Pavel
