Here is an interesting observation (I think). I have a demo program that makes strong use of the GPU. Here is what happens with two close kernel versions:
* 5.3.0-45-generic => everything ok, no hang, no noise * 5.3.0-46-generic => I CAN HEAR COIL NOISE when running the demo! And the whole system FREEZES (as described above) regularly for 3-4 seconds, every 20 to 40 seconds, and dmesg shows Apr 8 08:31:47 XPS-13-9350 kernel: [ 1604.860896] i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0 Apr 8 08:31:47 XPS-13-9350 kernel: [ 1604.861939] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Apr 8 08:32:51 XPS-13-9350 kernel: [ 1668.814516] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Apr 8 08:33:13 XPS-13-9350 kernel: [ 1690.794398] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Apr 8 08:33:39 XPS-13-9350 kernel: [ 1716.814185] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 This is on XPS13 with intel graphics. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861395 Title: system hang: i915 Resetting rcs0 for hang on rcs0 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1861395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
