Hi! I am seeing messages like the following during startup: [drm:amdgpu_get_bios [amdgpu]] *ERROR* ACPI VFCT table present but broken (too short #2) AMD-Vi: Event logged [IO_PAGE_FAULT device=00:00.0 domain=0x0000 address=0x00000000fffc0000 flags=0x0070] [drm:dce_v11_0_set_pageflip_irq_state [amdgpu]] *ERROR* invalid pageflip crtc 5 [drm:amdgpu_irq_disable_all [amdgpu]] *ERROR* error disabling interrupt (-22) amdgpu 0000:01:00.0: Fatal error during GPU init [TTM] Memory type 2 has not been initialized The first message always appears, while the others are not as easily reproducable. Other weird behaviour I notice is: * Hangs of the entire system when I start Steam using `env DRI_PRIME=1 steam` (nothing reacts to commands anymore, including mouse clicks, the power button and the num-lock key, and the mouse cursor moves very sluggishly) * Crashes of KWin when using Alt+Tab [1] * The firmware and GRUB (and Linux, initially) display at 1024x768, while the monitor's native resolution is 2560x1080. After the Linux kernel takes over, the monitor switches back to the native resolution. I would hope that someone could guide me in gathering more information about this and in the best case getting additional output or a backtrace from the kernel, please. Please find the full output of dmesg, lshw, lspci, glxinfo attached. Since the second card (RX 560) did not come up during this boot, I could not include the output of glxinfo for that card (`env DRI_PRIME=1 glxinfo`) at this time. I run Gentoo Linux with following software: * Linux 4.13.8 * Mesa 17.2.3 * LLVM 5.0.0 I have two graphics cards plugged in: * AMD Radeon R7 / AMD A10-7800 * AMD Radeon RX 560 The monitor is connected via Display Port to the first card (R7). If more information would be helpful, please tell me how and I will try to acquire it. --Dennis P.S. I accidentally sent this email to the dri-devel mailinglist before. Please excuse the noise and ignore it there. [1]: https://bugs.freedesktop.org/show_bug.cgi?id=103234 -------------- next part -------------- A non-text attachment was scrubbed...
