Looks like this is someone else's bug then. Do we have the resources to try to
investigate which driver is causing the corruption? My first strategy would be
to blacklist some modules, try to reproduce, blacklist others, try again and
see if it helps.

Perhaps we should report this at bugzilla.kernel.org?
