https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D232704 Bug ID: 232704 Summary: [regresion] top -SH wrongly shows CPU/WCPU on fully-loaded system Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: lev@FreeBSD.org top -SH on 13-CURRENT (r339662) doesn't show NIC interrupts. Here is screenshot under high network load, It could be seen, that 50% (one core of dual-core machine) is consumed by system, but there is no process/thread which consumes CPU: # top -HSIzts1 last pid: 3261; load averages: 0.60, 0.26, 0.23=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20 up 0+12:55:34 13:17:05 117 threads: 3 running, 101 sleeping, 13 waiting CPU: 0.0% user, 0.0% nice, 50.0% system, 0.0% interrupt, 50.0% idle Mem: 4448K Active, 15M Inact, 198M Wired, 20M Buf, 3716M Free Swap: PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND 0 root -76 - 0 2816K - 1 0:28 0.08% kernel{if_config_tqg_0} 11 root -60 - 0 1664K WAIT 1 0:23 0.07% intr{swi= 4: clock (0)} 3169 lev 20 0 17M 7740K select 1 0:00 0.02% sshd 698 root 20 0 18M 18M select 1 0:03 0.01% ntpd{ntp= d} 6 root -16 - 0 128K - 1 0:02 0.00% rand_harvestq 16 root -16 - 0 384K psleep 1 0:02 0.00% pagedaemon{dom0} 18 root -16 - 0 384K qsleep 1 0:01 0.00% bufdaemon{bufdaemon} 795 root -16 - 0 128K nfscl 1 0:00 0.00% nfscl 754 root 52 0 10M 2696K rpcsvc 1 0:00 0.00% nfscbd{nfscbd: master} 19 root 16 - 0 128K syncer 1 0:01 0.00% syncer 16 root -16 - 0 384K umarcl 1 0:00 0.00% pagedaemon{uma} 20 root -16 - 0 128K vlruwt 1 0:00 0.00% vnlru 18 root -16 - 0 384K - 1 0:00 0.00% bufdaemon{bufspacedaemon-0} 18 root -16 - 0 384K - 1 0:00 0.00% bufdaemon{bufspacedaemon-1} If load is lower (one core is not consumed), CPU consumption is attributed= to "kernel{if_config_tqg_0}" and/or "kernel{if_config_tqg_1}". I can not reproduce it on 11.2-STABLE. --=20 You are receiving this mail because: You are the assignee for the bug.=
