It's a few days late, but I was waiting for some updates for some of the most annoying regressions until releasing it, so the end result is hopefully more useful as a result.

Still crashes in acpi_get_data for me; the patch mentioned <[email protected]> and tracked at

http://bugzilla.kernel.org/show_bug.cgi?id=10132

still doesn't seem to have hit mainline and still fixes the issue for me.
