It doesn't work well with the defa= ult sizing algorithm that is greedy and tries to reserves more space than is re= ally required. Maybe the attached patch helps more devices to assign their resources: So please test with pci=3Drealloc,min_bridge_window It could still leads to a failure or some failures because it seems there simply is not enough space to fit everything even without pci=3Drealloc res= erving that extra empty space. Please also add dyndbg=3D"file drivers/pci/*.c +p" on kernel cmdline to get= a bit more information. --=20 You may reply to this email to add a comment.
