Hi, it is interesting - why on Yeeloong only ? Why it is not needed on "normal" GRUB ? And another idea - could be there some problem with PCI memory mapped register access caching ? Some Linux drivers uses so called "barrier" when doing access to PCI memory to be sure that previous access was really done - could be there such case ?
