[Bug 38228] ACPI broken on IBM ThinkPad R40e (fix)

[repvik]

Public bug reported:

Affects: linux-source-2.6.15 kernel-image-2.6.15-19-386-di (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
The BIOS on the R40e is broken, hangs when the processor module is
loaded. The fix for this is adding the following lines to
processor_idle.c:

{set_max_cstate, "IBM ThinkPad R40e", {
DMI_MATCH(DMI_BIOS_VENDOR,
"IBM"),
DMI_MATCH(DMI_BIOS_VERSION,
"1SET70WW") },
(void*)1},

The other revisions of the same BIOS has been blacklisted, this one has
not. It should go directly after the entry for "1SET68WW". I'm currently
unable to create a diff to do it.
