And you may get more than one and then this skips even though the test passed. Looks like the patch is overcompensating. What you can do is repeat the test a few times, and then look at all the different errors you get. If the connector remains (no mst disappareance) once it goes bad, it should remain bad and so not generate any new uevent. Or you only repeat the test whilst link_status[old] != link_status[new]. -Chris _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
