Re: system 20% busy at all times?
Hi,
On Feb 19, 2013, at 17:58, Adrian Chadd adr...@freebsd.org wrote:
Try top -HS .. to try and break down the kernel threads.
ACPI is eating the cycles, according to top:
0 root 80 0K 496K - 2 1:13 27.88%
kernel{acpi_task_2}
0 root 80 0K 496K - 0 1:13 25.68%
kernel{acpi_task_1}
0 root 80 0K 496K CPU11 1:07 23.68%
kernel{acpi_task_0}
I got an off-list hint that the machine in question requires device mptable
instead of relying on ACPI. I will try that.
As for dtrace, a complete buildworld/installworld cycle didn't change things, I
still get:
# dtrace -n 'syscall:::entry { @num[execname] = count(); }'
dtrace: invalid probe specifier syscall:::entry { @num[execname] = count(); }:
/usr/lib/dtrace/psinfo.d, line 90: failed to resolve type kernel`struct
thread * for identifier curthread: Module is no longer loaded
Thanks for all the help!

system 20% busy at all times?
Hi, I have a system running -CURRENT that in top(1) is showing ~20% CPU usage for the system at all times. Any ideas what could be causing this, or how I would go about diagnosing this further? Nothing in the logs. Thanks, Lars PS: dmesg attached, in case it helps: Copyright (c) 1992-2013 The FreeBSD Project.

Why? And indeed we find your answer here, acpi0 firing up a lot of interrupts. Don't you get any message about that in dmesg -a or /var/log/messages ? I'd expect something like interrupt storm blabla… source throttled blabla.. From man 4 acpi , in /boot/loader.conf : hint.acpi.0.disabled=1 Set this to 1 to disable all of ACPI. If ACPI has been disabled on your system due to a blacklist entry for your BIOS, you can set this to 0 to re-enable ACPI for testing. Any chance you could reboot the host with ACPI disabled ? If that helps your CPU load, try setting this in /boot/loader.conf : hw.acpi.verbose=1 Turn on verbose debugging information about what ACPI is doing. Hoping this gets some logs :) ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Re: system 20% busy at all times?
Completely disabling ACPI rarely works with modern machines.
Please try to run the following DTrace script (dtrace -s script-file) and
capture its output.
#pragma D option flowindent
fbt::acpi_intr_handler:entry
{
self-trace = 1;
}
fbt:::entry
/self-trace/
{
printf(arg0 = %#x, arg1 = %#x, arg2 = %#x, arg0, arg1, arg2);

exit(0);

FWIW, a full buildworld/installworld of the latest -CURRENT also didn't help,
the error remains.

If ACPI has been disabled on your system due to a blacklist entry for your BIOS, you can set this to 0 to re-enable ACPI for testing. Any chance you could reboot the host with ACPI disabled ? If I do that, I get an early kernel crash: Loading 10.11.12.13/~elars/kernel/kernel:0x20/7634255 0xb47d50/473552 0xbbb720/890736 Entry at 0x802746f0 Closing network.

Done, but it doesn't really result in any additional messages: # dmesg | grep -i acpi Features=0xbfebfbffFPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE ACPI APIC Table: PTLTD CARNEGIE acpi0: PTLTD CARNEGIE on motherboard acpi0: Power Button (fixed) cpu0: ACPI CPU on acpi0 ACPI Error: [\134_SB_.PCI0.LPC0.BCMD] Namespace lookup failure, AE_NOT_FOUND (20130117/psargs-393) ACPI Error: Method parse/execution failed [\134_PR_.CPU0._OSC] (Node 0xfe0007630c00), AE_NOT_FOUND (20130117/psparse-560) ACPI Error: [\134_SB_.PCI0.LPC0.BCMD] Namespace lookup failure, AE_NOT_FOUND (20130117/psargs-393) ACPI Error: Method parse/execution failed [\134_PR_.CPU0._OSC] (Node 0xfe0007630c00), AE_NOT_FOUND (20130117/psparse-560) ACPI Error: Method parse/execution failed [\134_PR_.CPU0._PDC] (Node 0xfe0007630c40), AE_NOT_FOUND (20130117/psparse-560) cpu1: ACPI CPU on acpi0 cpu2: ACPI CPU on acpi0 cpu3: ACPI CPU on acpi0 atrtc0: AT realtime clock port 0x70-0x71 irq 8 on acpi0 attimer0: AT timer port 0x40-0x43,0x50-0x53 irq 0 on acpi0 Timecounter ACPI-fast frequency 3579545 Hz quality 900 acpi_timer0: 24-bit timer at 3.579545MHz port 0x1008-0x100b on acpi0 pcib0: ACPI Host-PCI bridge port 0xcf8-0xcff on acpi0 pci0: ACPI PCI bus on pcib0 pcib1: ACPI PCI-PCI bridge at device 2.0 on pci0 pci1: ACPI PCI bus on pcib1 pcib3: ACPI PCI-PCI bridge at device 4.0 on pci0 pci3: ACPI PCI bus on pcib3 pcib4: ACPI PCI-PCI bridge mem 0xdeb0-0xdeb1 irq 16 at device 0.0 on pci3 pci4: ACPI PCI bus on pcib4 pcib7: ACPI PCI-PCI bridge irq 5 at device 8.0 on pci4 pci7: ACPI PCI bus on pcib7 pcib29: ACPI PCI-PCI bridge irq 16 at device 28.0 on pci0 pci29: ACPI PCI bus on pcib29 pcib30: ACPI PCI-PCI bridge irq 16 at device 28.4 on pci0 pci30: ACPI PCI bus on pcib30 pcib31: ACPI PCI-PCI bridge irq 17 at device 28.5 on pci0 pci31: ACPI PCI bus on pcib31 pcib32: ACPI PCI-PCI bridge at device 30.0 on pci0 pci32: ACPI PCI bus on pcib32 acpi_button0: Power Button on acpi0 uart0: 16550 or compatible port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 uart1: 16550 or compatible port 0x2f8-0x2ff irq 3 on acpi0 Jeez, I certainly hope people more knowledgeable than me about the kernel will be able to make something of all this. What about a newly build kernel without the line device acpi and without the options ACPI_DEBUG ?
