[Bug 11603] Re: ACPI PnP on Intel MU440EX

Thanks for opening this bug report, Martin.

The DSDT definitely includes the parallel device.  The device can be
in several modes, so there are actually three sections for it: LPT,
EPP, and ECP.  None of them showed up in the PNP debug output, so the
_STA methods must be telling us the device isn't present at all.

If you turn on CONFIG_ACPI_DEBUG and boot with these options:
  acpi.debug_layer=0x10000 acpi.debug_level=0x10

we should see the results of evaluating _STA.

Does the BIOS setup screen have any config items related to the
parallel port?  If so, can you experiment with them and find out
whether they make any difference?
