I updated my BIOS to the current version ~ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date JBET66WW (1.30 ) 09/13/2017
It didn't fix the [Firmware Bug] lines in the syslog though Also the actual bug still appears. There seem to be some lines in the log that I haven't seen before though Nov 3 12:37:05 xxx kernel: [ 8137.161988] [drm:pipe_config_err [i915]] *ERROR* mismatch in pixel_rate (expected 148500, found 296999) Nov 3 12:37:05 xxx kernel: [ 8137.162024] [drm:pipe_config_err [i915]] *ERROR* mismatch in shared_dpll (expected ffff9818ca8b46e0, found ffff9818ca8b47 78) Nov 3 12:37:05 xxx kernel: [ 8137.162051] [drm:pipe_config_err [i915]] *ERROR* mismatch in base.adjusted_mode.crtc_clock (expected 148500, found 296999 ) Nov 3 12:37:05 xxx kernel: [ 8137.162076] [drm:pipe_config_err [i915]] *ERROR* mismatch in port_clock (expected 270000, found 540000) Nov 3 12:37:05 xxx kernel: [ 8137.162078] pipe state doesn't match! Can you advise on how to narrow down the error to the actual state where it happens? Can it be achieved through changing settings in /etc/systemd/logind.conf? Because currently the only way to reproduce it is locking the screen while the computer is sitting in the docking station and come back after a longer period of time (e.g. 30 minutes) ** Bug watch added: Red Hat Bugzilla #1506339 https://bugzilla.redhat.com/show_bug.cgi?id=1506339 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1727662 Title: Crashes after unlock: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1727662/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
