I still do think there is a race going on h= ere; but my current thought is it might actually be related to how long it takes= for internal restore of the GPU when the VRAM is larger. One of the proposals was to make a device link via a quirk, which doesn't s= cale too well. But we could try to do a device link when an APU has XHCI and display under a common root port. Can you try this patch? It's intentionally going to be noisy at probe so y= ou can confirm it actually made the link. --=20 You may reply to this email to add a comment.
