Hi The conflict between pmac_zilog and the 8250/16550 driver still exists in the latest daily images. Is there any other way around the issue besides patching the source for 8250.c?
Is there a way to change the order in which the kernel attempts the drivers, to have pmac_zilog go before 8250.c? I can't really fix this myself, because I can't get a working debian installation to do it on. Anyone have a workaround?
