Seems like the bug is back. It pops up occasionally (one error line every ~2 hours) on Linux 6.5.0-14, 6.6.0-14 and 6.8.0-20. Appears on both Jammy: Xorg (Mate) and Mantic: Xorg/Wayland (Mate/KDE). Default kernel cmdline. On Xorg the graphics is fine, but on Wayland it can a bit "flickery" at times but it's barely noticeable. Machine is XPS13 9350.
``` kernel: i915 0000:00:02.0: [drm] *ERROR* Atomic update failure on pipe A (start=582395 end=582396) time 9696 us, min 1073, max 1079, scanline start 733, end 268 ``` Please let me know if there is any additional information you need. P.S. Not necessarily related, but I also see: ``` kernel: workqueue: engine_retire [i915] hogged CPU for >10000us 8 times, consider switching to WQ_UNBOUND among others like: kernel: [130525.417342] workqueue: set_brightness_delayed hogged CPU for >10000us 32 times, consider switching to WQ_UNBOUND kernel: [153420.843667] workqueue: smp_call_on_cpu_callback hogged CPU for >10000us 2048 times, consider switching to WQ_UNBOUND kernel: [168386.280902] workqueue: delayed_fput hogged CPU for >10000us 512 times, consider switching to WQ_UNBOUND kernel: [192582.937788] workqueue: intel_atomic_cleanup_work [i915] hogged CPU for >10000us 4 times, consider switching to WQ_UNBOUND ``` But that might be the scheduler getting confused on this aging and overloaded machine... -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1806242 Title: kernel: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A/B/C To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1806242/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
