Sorry for jumping in late, but did you verify MST with this change ?
Just a guess but MST relies on hpd_rx interrupt for messages and
disabling to early might have impact. Maybe trying unload/reload with
MST display to be sure ?

By moving amdgpu_irq_disable_all earlier in the sequence
fixes an issue with disabling pflip interrupts:
*ERROR* dal_irq_service_dummy_ack: called for non-implemented irq source
Earlier patch fixed a memory corruption and revealed irq
warnings.This way it seems to be there no obvious issues
with unloading the module.
