could not map ACPI

[Robert Woerle Paceblade/Support <robert-fPtsKRK0pHxl57MIdRCFDg@public.gmane.org>]

Hi

When i use mem=XXXM ACPI works fine , BUT i get cruel crashes when using 
  Sound and Ethernet or/and usb togethere ( they all have IRQ 5 ) one 
device alone is fine .
When i dont use mem=XXXM i get an error at /drivers/acpi/tables/tb_get.c
BUT all the devices work fine , even together !!!
i tried also mem=XXXM + acpi=nopci  which gives the same result : ACPI 
works and the devices crash together ....
the machine is a Transmeta driving machine ...

So when i look at tb_get.c at the specific functions...
i see that it maps the pointers there according to a 
switch(adress->pointer) call !
Is possible that it normally uses the
case ACPI_LOGMODE_PHYSPTR:
stuff but when i use mem=XXX
it might use the other case statement:
case ACPI_LOGMODE_LOGPTR:

can i make a cruel hack around that that it always uses the working one ???

The aim is of course to get both variants together : ACPI working + 
DEvices not crashing !!
Please advice !!!




---tb_get.c---- where it bails out--------

		status = acpi_os_map_memory (address->pointer.physical, sizeof 
(acpi_table_header),
				  (void **) &header);
		if (ACPI_FAILURE (status)) {
			ACPI_REPORT_ERROR (("Could not map memory at %8.8X%8.8X for length %X\n",
				ACPI_HIDWORD (address->pointer.physical),
				ACPI_LODWORD (address->pointer.physical),
				sizeof (acpi_table_header)));
			return_ACPI_STATUS (status);
		}
