[Kernel-packages] [Bug 1813423] Re: Frequent system freezing with i915 error "*ERROR* Atomic update failure on pipe A"
I understand that every user would like every bug they file to be considered "Important". In this case though we have around 23 people who have confirmed this bug affects them on the three separate bug reports. It causes hanging and forced hard shutdowns at unpredictable times as often as every 15 minutes or so. This means there is a high probability of user data loss and even hardware damage. I respectfully submit that it's reasonable to expect the importance of this to be set to High. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1813423 Title: Frequent system freezing with i915 error "*ERROR* Atomic update failure on pipe A" Status in linux package in Ubuntu: Confirmed Status in xserver-xorg-video-modesetting package in Ubuntu: New Bug description: My system keeps freezing on a brand new install of Kubuntu 18.10, always with the kern.log error "[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=4120234 end=4120235) time 486 us, min 763, max 767, scanline start 760, end 783" I think it's probably a duplicate of these bugs which were closed unresolved: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1660619 (closed as it was on an older version of Ubuntu) https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1671975 (closed because it was a duplicate of the first bug) It happens far more frequently if I have desktop effects turned on, and far less frequently when using a live USB key (at always happens eventually though.
