Well at least we know where the port is now - thats too fast for an LPC bus device, so it must be an SMI trap. Only easy way to find out is to use the debugging event counters and see how many instruction cycles are issued as part of the 0x80 port. If its suprisingly high then you've got a firmware bug and can go spank HP. -- 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/
