I'm using vgaswitcheroo to disable the Radeon in Linux. I'm on Arch Linux, I wasn't seeing the problem in kernel 4.5.0 but I'm seeing it now in 4.5.1. The kernel spits out errors about the atombios being stuck in a loop and then fills dmesg with messages about "ring 3 stalled". After about a full minute of this, X starts on the Intel GPU and the system seems to run normally. The kernel continues to spit out error messages during operation. Adding radeon.runpm=0 to the kernel parameters results in a normal boot, where the driver starts up normally and X starts up much more quickly. I do see that a patch related to runtime PM (e64c952efb8e0c15ae82cec8e455ab4910690ef1) went into the kernel recently. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
