Hi Karol.
I sent the originsl report to Ben and LKML. Thorsten then added you, Lyude Paul and the dri-devel and nouveau lists. So you should have received this report on or about January 19.

Where was the original email sent to anyway, because I don't have it at all.
Anyhow, I suspect we want to fetch logs to see what's happening, but
due to the nature of this bug it might get difficult.
I'm checking out the laptops I have here if I can reproduce this
issue, but I think all mine with Turing GPUs are fine.
Maybe Ben has any idea what might be wrong with
0e44c21708761977dcbea9b846b51a6fb684907a or if that's an issue which
is already fixed by not upstreamed patches as I think I remember Ben
to talk about something like that recently.
