Your rc3-mm3 boot is also missing this:
IOC: zx1 2.2 HPA 0xfed01000 IOVA space 1024Mb at 0x40000000
So something's busted with ACPI. Both the IOC and the rx2600 serial ports should be discovered via ACPI. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
