Product: Drivers Version: 2.5 Kernel Version: 4.15.15 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: smf.linux@ntlworld.com Regression: No

Created attachment 275347 --> https://bugzilla.kernel.org/attachment.cgi?id=275347&action=edit Some dmesg data

Getting a few (3-4 over 2-3 weeks) graphics lockups. The screen goes to a random light grey pattern with a large square cursor. Usually the lockup is solid but on one occasion I was able to ssh in from another machine and capture some dmesg data (attached).

The graphics card is new (11th March) and replaces an older Turks model which was trouble free in this machine. Details of the new card are as follows: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland PRO [Radeon R7 240/340]

Any suggestions ?

Thanks
