Subject: amdgpu dumping during boot in picasso

I recently upgraded the mobo in an old machine to now use a Ryzen 5
3400G (Picasso APU). With 5.3 kernels it seems to be running well, but
an unrelated issue caused me to look at dmesg: it dumps during boot,
and then there may be related dumps later, possibly from resuming from
suspend or hibernation. The earliest usable kernel is 5.0 (Picasso is
too new for original 4.19 which doesn't load amdgpu) and it turns out
that all kernels up to and including linus's tree of a few hours ago
do this. From linus's tree:
