That sadly looks vaguely familiar... I think its the point where I gave
up chasing bugs last year, because I was going soft in the head staring
at this stuff for several months non-stop.

It taking several hours to reproduce didn't help.

I suspect its something iffy with the Intel driver, because I could
never trigger it on AMD, but of course, no guarantees ...

I'll try and find some time again to chase this down once Alexander
sorts that AUX issue.
