Matthieu Baerts, could you please test the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/ and advise to the results?
** Description changed: - Hello, - - I'm using Ubuntu Raring 13.04 with the latest version of the kernel - available in these repos (3.8.0-19.29). - - Sometimes I have a kernel OOPS at startup and it seems it's because I switch off my ATI card. + With using Kernel 3.8 and newer sometimes I have a kernel OOPS at startup and it seems it's because I switch off my ATI card. I added this line in my /etc/rc.local file: - echo OFF > /sys/kernel/debug/vgaswitcheroo/switch + echo OFF > /sys/kernel/debug/vgaswitcheroo/switch I don't have this bug each time but I guess it depends if this previous - command is launched before or after that X11's launch. - - I'm using this card: Mobility Radeon HD 4650. + command is launched before or after that X11's launch. I'm using this + card: Mobility Radeon HD 4650. It seems that this bug has already reported to there: https://bugzilla.kernel.org/show_bug.cgi?id=49531 and https://bugs.freedesktop.org/show_bug.cgi?id=61529 But I guess it can be interesting to track this bug on Launchpad.
