I tried to apply the patch to 2.6.0-test2 in hope that this resolves my
oops during boottime on my thinkpad t40p.

Unfortunatly the compilation of the kernel fails with:

-----------------------------------------------------------------------------
CC drivers/acpi/pci_link.o
drivers/acpi/pci_link.c: In function `acpi_pci_link_allocate':
drivers/acpi/pci_link.c:451: `_dbg' undeclared (first use in this function)
drivers/acpi/pci_link.c:451: (Each undeclared identifier is reported
only once
drivers/acpi/pci_link.c:451: for each function it appears in.)
make[2]: *** [drivers/acpi/pci_link.o] Error 1
make[1]: *** [drivers/acpi] Error 2
make: *** [drivers] Error 2
-----------------------------------------------------------------------------

Any ideas how to port your patch to the 2.6 series ?
