If you refer to "PCI quirk: RS780/RS880: work around missing MSI
initialization", the system only has a RS690.
And as far as I know, MSI works for the graphics part:
~ # grep radeon /proc/interrupts
 25:          1        909   PCI-MSI-edge      radeon

(I'm only using fbcon, no Xserver running)

But please note: The only problem is the 6 second delay during HDMI
audio initialization. And that was not fixed by
snd_hda_intel.enable_msi=0.
As I don't have any hardware to attach to the HDMI port, I probably
can't help you debugging this further then "the delay is gone".

Thanks, Torsten
