https://bugzilla.kernel.org/show_bug.cgi?id=61891 Bug ID: 61891 Summary: Cannot switch off Radeon 6400M with vgaswitcheroo Product: Drivers Version: 2.5 Kernel Version: 3.12-rc1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: madcatx@xxxxxxxx Regression: No Created attachment 109251 --> https://bugzilla.kernel.org/attachment.cgi?id=109251&action=edit dmesg I use systemd's tmpfiles to power off the Radeon DIS early during boot to save power. This works fine with kernel 3.11.1 but it breaks with 3.12-rc1. I removed the systemd rule and tried to power the card off manually (echo OFF > /sys/kernel/debug/vgaswitcheroo/switch). I got a kernel warning and vga_switcheroo died. See the attached file for full dmesg dump. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
