Hi Shixiong / Shuang, according to the 6.8.0-58.log in #59, you are not experiencing the issue anymore, am i correct?
As mentioned in #56, our bisect was at this point: 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 ... 7fdb45c9bbbc (tag: Ubuntu-6.8.0-31.31, refs/bisect/good-7fdb45c9bbbc95a3300b4d8de3f751f4c05c98e2) UBUNTU: Ubuntu-6.8.0-31.31 In particular, all those workqueue patches were reverted upstream on v6.8.4: https://github.com/gregkh/linux/commits/v6.8.4/ because they were causing several regressions - so any kernel that has those reverts, should be good.
