You cannot "switch to radeonsi", I assume you mean when you use the radeon
kernel driver instead of amdgpu. The Mesa radeonsi driver is used in both
cases.

You might want to try a kernel built from the amd-staging-drm-next branch of
https://cgit.freedesktop.org/~agd5f/linux/ with CONFIG_DRM_AMD_DC=y at build
time and amdgpu.dc=1 at runtime, to see if that works better.
