Hmm. The scheduler changes seem to show problems with suspend/resume.
I now get his when suspending:
... Disabling non-boot CPUs ... Cannot set affinity for irq 285 smpboot: CPU 1 is now offline ------------[ cut here ]------------ WARNING: CPU: 2 PID: 25 at kernel/sched/sched.h:812 update_load_avg+0x779/0xa70 rq->clock_update_flags < RQCF_ACT_SKIP ... Call Trace: update_load_avg+0x779/0xa70 set_next_entity+0xd9/0x220 pick_next_task_fair+0x88/0x550 sched_cpu_dying+0x1cf/0x2a0 cpuhp_invoke_callback+0x80/0x3b0 take_cpu_down+0x5e/0xa0 multi_cpu_stop+0xb6/0xe0
the issue may have been going on for a while, but the new WARN_ON() was added in this merge window.
(Not sure how consistent this warning is, it definitely doesn't happen every time, I've only seen it once)
