Interesting. This is due to a change in current git it was not present
in 2.6.29.
Does booting with acpi_osi=Linux makes things any worse? (it should fix
the above error but might make some other functionality behave
differently).
Or eventually also see if there is a bios upgrade available for your
laptop.
Len,
it looks like most of the vaios define this in global scope:
OperationRegion (PRT0, SystemIO, 0x80, 0x04)
Field (PRT0, DWordAcc, Lock, Preserve)
{
P80H, 32
}
which falls in the DMA1 reserved area in >WinXP.
No idea how windows copes with it if the same restrictions area really
in place.
