Sorry, I meant the VIA DRM driver.

I suspect that's getting warmer.

For long-term bugs like this one it's best to track it in
bugzilla.kernel.org.  I'd suggest that you assign it to
acpi_config-interrupts@...nel-bugs.osdl.org and add airlied@...ux.ie to the
cc.

It'll take a while, but these things often do end up fixed.
