Yeah plus Cc: stable for backporting and I think an igt or similar for panfrost to check this works correctly would be pretty good too. Since if it took us over 1 year to notice this bug it's pretty clear that normal testing doesn't catch this. So very likely we'll break this again.
I made the IGT test below which seems to reproduce the bug. However, the kernel patch doesn’t fix it, so maybe there is something more subtle going on.
