--- Comment #21 from Dave Airlie airlied@freedesktop.org 2012-02-12 08:59:56 UTC --- Alex I think this is a driver or hw bug actually.
I seem to lose MSI rearms here, if I manually poke a rearm in from userspace over ssh the system recovers fine.
not sure if we should disable MSI on rv515, you might be able to find some info internally.
