Firstly I've had four 'lockups' since 17 Jan, none of which contain the [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring idle issue. Secondly since 14 Jan when I went back from the 3.14* kernel build to Ubuntu's 3.13.0-44-generic I've been seeing quite often in my syslog: kernel: [ 1326.412487] [drm:intel_crtc_cursor_set_obj] cursor off kernel: [ 1326.412493] [drm:g4x_check_srwm] SR watermark: display plane 92, cursor 2 kernel: [ 1326.412495] [drm:g4x_check_srwm] display watermark is too large(92/63), disabling kernel: [ 1326.412497] [drm:intel_set_memory_cxsr] memory self-refresh is disabled kernel: [ 1326.412499] [drm:g4x_update_wm] Setting FIFO watermarks - A: plane=40, cursor=2, B: plane=2, cursor=2, SR: plane=0, cursor=0 I might add that though the system 'appears' to be 'locked up' it is only the video that is locked, however the mouse cursor will continue to move, if that makes any sense. The system continues to fetch and process mail with fetchmail and procmail, SpamAssassin and ClamAv continue to run as well as scripts I have to report spam and so forth. Whether this change will make any difference in this bug report I'm not sure. Since the status of this report shows 'Need Info' still I'm not sure what else can be added to it.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
