Thank you.

I will first try to reintroduce the kernel parameters I previously used. Do you
think those can help at all?

CPU
rcu_nocbs=0-15 (adjust to the number of cores of your cpu)
idle=nomwait
processor.max_cstate=5
pcie_aspm=off 

GPU
amdgpu.dc=1
amdgpu.vm_update_mode=0
amdgpu.dpm=-1
amdgpu.ppfeaturemask=0xffffffff
amdgpu.vm_fault_stop=2
amdgpu.vm_debug=1
amdgpu.gpu_recovery=0
