Carlos, could you please run the following script as root: http://redhat.com/~mingo/misc/probe-ports.sh and send us the resulting probe-ports.txt file? This script will probe all unused ports as per /proc/ioports and will list "suspect" IO port areas: ones that do not produce the expected 0xff default reply from unclaimed IO ports. Magic chipset register areas can potentially be mapped this way. [ CAREFUL: This probes IO ports which might in theory trigger various nastiness such as lockups. I this on a few boxes and the script worked, but save any work in case you get lockups. ] Ingo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
