Comment 40 for bug 551668

I think this is either a dupe of bug #819002 or should be fixed in a similar manner. (I.e., the patch on that bug might not fix this particular model, but it might simply require adding this model number.) The fix improves the ACPI support for Vaios in the linux kernel.

In particular, since you indicate the problem also exists with -nouveau, that seems to narrow it to the kernel as well.

Reassigning to the kernel. Possibly this should be duped to #819002, but I'm not certain.
