--- Comment #4 from Alex Deucher alexdeucher@gmail.com --- It's probably not a kernel bug then. More likely a bug in the 3D or vdpau driver or in flash. I just happens to manifest on 3.10 since that was the first kernel with UVD support. If you can narrow it down to flash or UVD, you may want to close this bug and open a mesa bug (https://bugs.freedesktop.org) against the r600 gallium driver.
