Almost a year later even after adjusting BIOS settings (SATA controller was trying to emulate ATA controller so I switched to AHCI) I kept seeing intr 16 on cpu0 at 40001/40000 hz, livelocked limit engaged! intr 16 on cpu0 at 11963/20000 hz, livelock removed even on the dfly# uname -a DragonFly dfly.bagdala2.net 4.8-RELEASE DragonFly v4.8.0.1.g86163-RELEASE #4: Tue Mar 28 07:56:27 EST 2017 [email protected]:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64 Then I stumbled recently on this post http://yrabbit.freeshell.org/en/2012/03/04/dragonfly-bsd-under-qemu.html and sure enough echo 'hw.ioapic_enable=0' >> /boot/loader.conf.local reboot made intr 16 on cpu0 at 40001/40000 hz, livelocked limit engaged! intr 16 on cpu0 at 11963/20000 hz, livelock removed disapear from dmesg. Unfortunatelly I don't know enough about Advanced Programmable Interrupt Controller https://en.wikipedia.org/wiki/Advanced_Programmable_Interrupt_Controller so I am not sure if the above is just bandage for an actual bug which looks like it should have being fixed http://lists.dragonflybsd.org/pipermail/bugs/2012-March/244444.html Thanks, Predrag > > On Sat, Apr 16, 2016 at 4:10 PM, Predrag Punosevac > <[email protected]> > wrote: > > > Sepherosa Ziehau wrote: > > > > > On Tue, Apr 5, 2016 at 11:09 AM, Predrag Punosevac > > > <[email protected]> wrote: > > > > Sepherosa Ziehau <[email protected]> wrote: > > > > > > > >> Please post the output of 'vmstat -iv' > > > > > > > > dfly# vmstat -iv > > > > interrupt total rate > > > > irq4 0: sio0 0 0 > > > > irq9 0: acpi0 0 0 > > > > irq16 0: ehci0/atapci0/atapci1 61925216594 35565 > > > > > > > > > I'd suspect its EHCI, do you have anything uses USB?
