Hi Aaro, Ivaylo,

Is there any progress on the issue? I tried 5.9.1 and still nothing displayed.

Can you test the attached patch?


With this patch I don't see oops that Aaro reported, so:

Tested-by: Ivaylo Dimitrov <ivo.g.dimitrov.75@xxxxxxxxx>

Seems to fix the particular issue, however, now we get another oops. As this is not upstream kernel but one with PVR related patches, I will try again with vanilla 5.9.

Just in case oops rings any bells (the line in question is https://github.com/maemo-leste/droid4-linux/blob/maemo-5.9/drivers/gpu/drm/omapdrm/omap_gem.c#L801)
