So there must be something different between your system and Edmund's.
Maybe we can refine the quirk so it avoids the SBR on Edmund's system
but not yours.
Can you both collect the output of "sudo lspci -vvv" so we can try to
figure out the difference? Also a complete dmesg log would be helpful
and would contain DMI information that we might need if this is
firmware dependent.

Edmund, could you run this command, too?
Thanks,
