Comment 46 for bug 187671

Looking at Arne's patch it does not look to be a general solution but a machine specific bodge. This would have undesirable effects on other machines which have the same hardware components but not the broken combination as in this machine. That makes it hard to see this patch making the mainstream kernel. What would appear to need to happen to make that possible is to find whatever is using the MMIO space and get that recognised. Not an easy task.
