--- Comment #53 from Andrey Grodzovsky andrey.grodzovsky@amd.com --- Created attachment 141198 --> https://bugs.freedesktop.org/attachment.cgi?id=141198&action=edit add_debug_info2.patch
Try this patch instead, i might be missing some prints in the first one. In the last log you attached I haven't seen any UMR dumps or GPU fault prints in dmesg. THe GPU fault has to be in the log to compare the faulty address against the debug prints in the patch.
