Yes both Rocket League and Desktop hangs seem to be the sdma0 type. I will add
that parameter as well and see if there is any difference with Rocket League
hang and use the desktop with both flags enabled.

Well I mean actually finding multiple bugs while debugging 1 can only be a good
thing, after all less bugs in the future and my personal computing seems to
have quite a few corner cases it seems that otherwise go unnoticed :D which
should benefit many new happy Navi users
