AMDGPU init broken (sw_init of IP block <uvd_v4_2> failed -19) between 5.19.0.29 and 5.19.0.31

[Asa Zernik]

After upgrading the linux kernel 5.19.0.{29=>31}, my external graphics card stopped being used on startup, and my system fell back to internal graphics. When using the previous kernel - a patch-level update only - this works fine.

Both the error on 5.19.0.31 and the continued proper function on 5.19.0.29 have persisted across multiple automatic and manual runs of update-initramfs, and across a downgrade and then upgrade of linux-firmware to/from the non-kinetic-updates version.

Full error trace from syslog and preceding lines about AMDGPU initialization progress are attached.
