I looked at the nvidia sources to check that the driver does not use the interfaces which KBI was changed, and this is indeed the case, as expected. I must admit that I have no idea why buffer cache changes could affect nvidia driver, and with no input on the panic (I hope that it is panic, and not a reset) have no idea even to speculate. So firewire cable is probably the must. Note that I split that import of the work into the series of commits. The split was done to ease the reading of the chunks, and individual commits were not functionally tested. Still, you might try to do the bisect. --BlSXMmufQQBIrxDX Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iQIcBAEBAgAGBQJRShdZAAoJEJDCuSvBvK1BkyAP/0eYepmislGuLChxPFuiybsT VkRdDsmsWR2dIwFeFhoSkGgE5WIjm5hI0GnavlPWHY3yTFCn07o6OLHXUu1YZWFE 2xliQJzUUwuCjp/zDnyW2tnCMo8/VGKShZn+ruOBvOphe9dfx2nuV0PHF4OAPb4e PowN2nFWO5OmDEHZZoF5POrRJn3Id6JKkhzE2tR1EOHKNGvStuNe5E7MvLfhqWYV VzUnMgK6a72vOYfC6tClOAYjWarNzZkcmK9Em8UyWuG1oNT0YJbFphmhShGrTJ0V bJ/GN4nDdHPjCUa5nr1XsYyElDv1ibHLx82rhSM0ZZsW+yIY0LlnW21MNk5aWEur 8z16s3B1Ls5AQtqYZWDX+yzdrUS9lqy6BGKkSPZeavrltiDdXRlp4/nwQ9LbOW6E X8ioBmmGpPXHQoOQGt1DqBhRlNMMv4yOfSdsvaOv6yzkdg9SYmGOZ+1m95GQvMdp N4AFFWbDOuVGywkL1ucovgsflVEKmqcBKXlHVLlSYZBaggXQmU1QXpnrStCKEPtx UroRubsCzd58+X1CP4HuzVPQ3xo+hSlQk+PYtU1xR4FX+5pZFzDUQN6/hgirtUlZ 6NXQJNBzygQiryP6KCGV1eEvvT1e2iTtAnQyY/BiVfTZBRULYWgfowj3hYBd84Fb WC0OVQfh0iGslpLlmLG1 =MFGk -----END PGP SIGNATURE----- --BlSXMmufQQBIrxDX--
