Thanks. I tried 5.9.1 and I think there's still a problem, or at least something different.
Using the same configuration script, I noticed that my cards are running a lot hotter. For example, here's total power consumption of a two-card system with two different kernels:
5.8.14: 460W 5.9.1: 560+W
Memory and system clocks are initially set the same on all cards in all cases.

Hello all, Regarding amdgpu, I've been using some Radeon 5700XTs for compute work with kernels through 5.8.14. I recently tried kernel 5.9.0, and found that the following is no longer allowed: echo "m 1 200" | sudo tee /sys/class/drm/card0/device/pp_od_clk_voltage Is this an expected change? If so, where should I look for documentation regarding how to manually configure these cards with this kernel. Note, I've had this working with 5.8 kernels for months.
It was a bug. Fixed in 5.9.1.
