Created attachment 136904 [details] Serial kernel console for Panic/BUG/OOPS bug on Kaveri+GFX8 Hi- I'm having issues with bringing up a kennel on an AMD Kaveri (A10-7850K w/ R7 iGPU disabled) using a Radeon Rx 480 8GiB. I'm using (at the time of this writing) the latest commit from agd5f's drm-next-4.17-wip branch (commit 006a62b26fbb0b7dcd8061f83889e0514ea42d17 ('drm/ttm: Don't unreserve swapped BOs that were previously reserved')). When bringing up the kernel, it acts like it's initializing the (DisplayPort-connected) display, but then the screen blacks out and the display finally goes to sleep. I've attached a kernel log (grabbed from a serial connection (the kernel panics too soon to bring up the various network devices, and thus the network console)), which hopefully has enough verbosity to be useful. It's also available at https://gist.github.com/Haifen/f783d5f6b2ab3d30805d9f5315b7c675 Please let me know if there's any more information you require. -Robin K.
