Hi,
can this be taken into .28 if it works out with acpica integration.
Patches are in OpenSUSE for quite a while now (also 11.0) and the
issue has been evaluate to the ground now.
Lenovo confirmed that some rare models which got Vista support added
late through BIOS upgrades could have wrong 64 bit addresses.
Vista also takes the broken 64 bit addresses like Linux does (spec conform).
XP does take the correct 32 bit addresses.
A generic approach (e.g. check through _OSI) does not work, because:
- the affected models support Vista (there the wrong addresses are also
taken, but
the symptoms seem not to happen or are also workarounded)
- Those IO addresses are touched before the DSDT is parsed -> no OSI
OS feature support check possible.
Be aware that one patch makes changes in ACPICA code.
Thanks,
Thomas
