New backtrace, this time running -current without any diff (not the one
bumping some thread pools to 4), and the hang was on schto, clearly
pointing at radeondrm methods. Hope it helps.

Fwiw, been running most of the day without hangs so far, so it seems that
toggling layers.acceleration.force-enabled & webgl.force-enabled to
false in my ffx profile has an effect.

If you want to reproduce this issue, might want to try with those turned
on..
