I have made an interesting observation: When booting disabling IOMMU with amd_iommu=off in the kernel command line the system seems to work fine yet. I haven't extensively tested this, but yet I have no crash while creating this comment, multiple successful reboots, and
$ glxinfo | grep Open reports: OpenGL renderer string: Gallium 0.4 on AMD CARRIZO (DRM 3.9.0 / 4.10.0-20-generic, LLVM 4.0.0) Also, glxgears supports vsync now, and when executing $ vblank_mode=0 glxgears the reported framerate is about ~10 times higher then with software rendering. The idea comes from a different bug, which however also differs in its description: https://bugs.freedesktop.org/show_bug.cgi?id=100591 ** Bug watch added: freedesktop.org Bugzilla #100591 https://bugs.freedesktop.org/show_bug.cgi?id=100591 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1683184 Title: GPU problems on HP 15-ba009ng To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1683184/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
