#10 is for cardbus bridges, IIRC. > 0x100000 is 1MB and would be the minimum MMIO range that can be allocated. > So that looks right too. Probably need to find out what is allocating > 0xe0000000 instead. I believe that the setup-bus code just tried to allocate 1M ROM of some device using prefetchable window of the bridge 0000:00:00.0. That failed, probably because there is no MEM space left on the root bus, which is perfectly OK. Then, the ROM might be successfully allocated in the non-prefetchable MMIO space. So, I don't see any problem in this situation. The only thing I could suggest is to lower the log level in that message from KERN_ERR to KERN_WARNING...
