Hi Shixiong, thanks for the report. At the moment the bisect sits here:
4d60b13f267d workqueue: Don't call cpumask_test_cpu() with -1 CPU in wq_update_node_max_active() adc1b642f72f workqueue: Implement system-wide nr_active enforcement for unbound workqueues 929b7fbecbcc workqueue: Introduce struct wq_node_nr_active afd774d513f5 workqueue: RCU protect wq->dfl_pwq and implement accessors for it 31a8e16645d7 workqueue: Make wq_adjust_max_active() round-robin pwqs while activating e4bbec8ce062 workqueue: Move nr_active handling into helpers 865f7641cf47 workqueue: Replace pwq_activate_inactive_work() with [__]pwq_activate_work() a88074533304 workqueue: Factor out pwq_is_empty() 5d378b3d47e1 workqueue: Move pwq->max_active to wq->max_active eb182ba1f6cb workqueue.c: Increase workqueue name length a0fcae282d10 do_sys_name_to_handle(): use kzalloc() to fix kernel-infoleak fa1cbadd64bc UBUNTU: [Packaging] add Real-time Linux Analysis tool (rtla) to linux-tools 888e7c48a1ff UBUNTU: SAUCE: rtla: fix deb build 51c8aee42179 UBUNTU: [Packaging] provide a wrapper module for python-perf 48357b9b6d27 UBUNTU: [Packaging] enable perf python module 759436dbdae1 drm/amdgpu: respect the abmlevel module parameter value if it is set 716ec855fa62 drm/amd/display: add panel_power_savings sysfs entry to eDP connectors b4275c751289 UBUNTU: Start new release 782e3646d110 UBUNTU: [Packaging] update annotations scripts b43457da65e4 UBUNTU: [Packaging] update variants 80ebe4152d65 UBUNTU: [Packaging] drop getabis data 7fdb45c9bbbc (tag: Ubuntu-6.8.0-31.31, refs/bisect/good-7fdb45c9bbbc95a3300b4d8de3f751f4c05c98e2) UBUNTU: Ubuntu-6.8.0-31.31 these workqueue patches are definitely suspicious, but they are actually part of the v6.8.2 stable tree hence i'm a bit puzzled - before we move forward, may i ask you to: 1) test the lastest v6.8 Noble kernel from proposed: linux-generic | 6.8.0-58.60 | noble-proposed | amd64, arm64, armhf, ppc64el, s390x 2) test again Noble GA kernel: linux-generic | 6.8.0-31.31 | noble | amd64, arm64, armhf, ppc64el, s390x I want to double check we didn't overlook anything.
