The hangs occurred with firmware from the AMD 20.50 release. I'm currently running with firmware from the 20.40 release, no hang in almost 2 weeks (the hangs happened within 1-2 days after boot).

Unfortunately not. After no hangs for two weeks with older firmware, I just got a hang again within a day with newer firmware and a kernel with this fix.

I'll try and narrow down which firmware triggers it now. Does Picasso use the picasso_*.bin ones only, or others as well?
