Bug ID: 106513 Summary: AMDGPU not working on ubuntu 18.04 Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: mathieu.dutour@gmail.com

Created attachment 139556 --> https://bugs.freedesktop.org/attachment.cgi?id=139556&action=edit the dmesg output

WHAT HAPPENS - Amdgpu refuses to start without any information as of why. - The problem happened between Ubuntu 17.10 and Ubuntu 18.04 - Three behaviors are occurring: a) The login happens normally (very rare, only 2 times) b) The login fails, the screen remain stuck and nothing happens c) The login fails and I am sent back to the login screen - The mouse cursor does not respond to movements. - I can access to the console via Ctrl+Alt F4 - The "dmesg" output is in attachment. The smoking gun in my opinion is [ 170.244044] [drm:atom_op_jump [amdgpu]] *ERROR* atombios stuck in loop for more than 5secs aborting

TIPS - I can access to login screen and to all the data on the computer. But only in text mode. So I can update

The crashes that allows ssh connection almost always happens when firefox is openned and running a video (netflix, youtube) or whatsapp web. - The crashes that simply hangs the entire computer may occur at any time.

OBSERVATIONS - No modification were done to the driver, only standard driver from ubuntu 18.04.

SYSTEM SPECS - Dell Inspiron 5767 is used. Kernel from Ubuntu
