With or without crossfire, I encounter the problem, and the graphic card in slot number one is always the one taking over. Also, I already set up a console over serial port, but nothing gets out when the system hangs. That's why i am now at the point of running the kernel under GDB. Also, I want to say that the problem does not occur on boot phase at all, everything goes just fine until I activate any other power profile than 'default' one on the radeon card using: # echo '(low|mid|high)' > /sys/class/drm/card0/device/power_profile Then, once power management activated, the system randomly hangs *AFTER* a various amount of time, requiring a hard reboot. > hth, James - -- YaGB on http://gentooist.com Follow me on twitter @blakawk -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJPCzVzAAoJEIJZqh3hgPiNWMQP/31y5wmf2Q+V6ZPx2vcHVw8C riEgI3mkwNylO+UWhJqAzDwjuvkmP+h53DHhWZD+PXfiSHDoSE3N9K56SwY3rTZx HvxgjO+qmdebFfB+hwBZkcFbSidU7exTA3GQnquE8Z/jRw+1MjnAUAs653rKA3wF DEv5cwtaJFNDQKKzGahMVkWrxN2JHMqGQ0gbk4d59IwzYPTrJFPc/mvDQxlIswWU K5UJvSIlHm9TsiHFGqUCK4ToKUe8+3KBGiF70tRzrxaez5HqJ8joMlKA6ZSpVBkh exzVZe2MWUx9prUBXEB6fQQn8vGKstallYJ9wHMmF0Mj2I13XoIXW2o6BIt2Qwt5 0qNrNRSSxam2mjTBQXX6NCGCPSa/Wo2lactAgRtIbS8a1wdH9GoY4SAwSNVWzv/8 muY4SOGcVhc403I3SaCV9cSxHfTAA+X1Nx6lWQlOo0SjDsHNpje8TXnSyLuX3z4h Aipp7fSuLI97tYDVsbHTZpoG8J4b84tqM2y2GIydAmG+S+LrYo5YQ6UaxKU3lGjo rC+mBnx8BPELGd/DhUMzGVzRFW1lFe9XlRXqYgh+7eJfldVYGXYUxW9YIEwutL/1 5QnupsXkWlT5AMYQ0iFIfqr+2TepBgzqGONmvHaQF8sElqGk2VeeRdqVoe9W8bbp L2+1PrNrtrjkw46ob3rf =YGxL -----END PGP SIGNATURE-----
