Firefox was animating its sidebar drawer close, when it suddenly froze. Surprisingly, GPU recovered and I'm writing this message in Firefox. Althought I see now's it constantly spewing "kernel: i915 0000:00:02.0: Resetting rcs0 for stopped heartbeat on rcs0" every 3 seconds. DRM card0 error log attached. EDIT while I was writing this message, machine suddenly went autonomously into suspend and, I think simultaneously, gnome-shell died with "i965: Failed to submit batchbuffer: Input/output error" ``` nov 09 19:42:53 papaya kernel: i915 0000:00:02.0: Resetting rcs0 for stopped heartbeat on rcs0 nov 09 19:42:56 papaya kernel: i915 0000:00:02.0: Resetting rcs0 for stopped heartbeat on rcs0 nov 09 19:42:59 papaya kernel: i915 0000:00:02.0: Resetting rcs0 for stopped heartbeat on rcs0 nov 09 19:43:02 papaya kernel: i915 0000:00:02.0: Resetting rcs0 for stopped heartbeat on rcs0 nov 09 19:43:05 papaya kernel: i915 0000:00:02.0: Resetting rcs0 for stopped heartbeat on rcs0 nov 09 19:43:08 papaya kernel: i915 0000:00:02.0: Resetting rcs0 for stopped heartbeat on rcs0 nov 09 19:43:11 papaya kernel: i915 0000:00:02.0: Resetting rcs0 for stopped heartbeat on rcs0 nov 09 19:43:14 papaya kernel: i915 0000:00:02.0: Resetting rcs0 for stopped heartbeat on rcs0 nov 09 19:43:14 papaya org.gnome.Shell.desktop[10561]: i965: Failed to submit batchbuffer: Input/output error nov 09 19:43:14 papaya polkitd[9832]: Unregistered Authentication Agent for unix-session:3 (system bus name :1.72, object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale et_EE.u tf8) (disconnected from bus) nov 09 19:43:14 papaya gnome-session[10493]: gnome-session-binary[10493]: WARNING: App 'org.gnome.Shell.desktop' exited with code 1 nov 09 19:43:14 papaya gnome-session-binary[10493]: WARNING: App 'org.gnome.Shell.desktop' exited with code 1 ``` After gdm restart, kernel log is staying clean, so looks like some kind of a graphics stack reset happened. (PS All hail Firefox, who successfully saved all typed work in the form, when the session died.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
