### On Thu, 29 Jan 2004 15:43:22 -0600, Jonathan Fosburgh ### <syjef@mdanderson.org> casually decided to expound upon ### freebsd-current@freebsd.org the following thoughts about "Re: unusually ### high load averages": JF> Run `top` and see what your interrupts are doing. I'd guess you're suffering last pid: 1011; load averages: 1.14, 0.93, 0.98 up 0+00:26:38 15:30:09 85 processes: 2 running, 73 sleeping, 10 waiting CPU states: 0.8% user, 0.0% nice, 0.8% system, 0.4% interrupt, 98.1% idle Mem: 35M Active, 94M Inact, 38M Wired, 2480K Cache, 34M Buf, 74M Free Swap: 1024M Total, 1024M Free PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 11 root -16 0 0K 12K RUN 22:39 98.83% 98.83% idle 661 root 96 0 42416K 33140K select 0:04 0.05% 0.05% XFree86 ... JF> from the IRQ20 storm. vmstat -i should also tell you that. A patch was # vmstat -i interrupt total rate irq0: clk 158958 99 irq1: atkbd0 5423 3 irq6: fdc0 2 0 irq8: rtc 203476 127 irq11: cbb0 cbb1++* 91496 57 irq12: psm0 11877 7 irq13: npx0 1 0 irq14: ata0 49687 31 irq15: ata1 57 0 Total 520977 327 JF> posted to this list in the last couple of weeks that deals with this. It is JF> working for me (I first ran into this a couple of days ago). I tried to apply the patch but it didn't go in cleanly so I'll have to hand-massage it. I did start running into this when I enabled ACPI because the apm module is causing my kernel to panic for some reason. However I also notice this when I have ACPI disabled too. -- /*===================[ Jake Khuon <khuon@NEEBU.Net> ]======================+ | Packet Plumber, Network Engineers /| / [~ [~ |) | | --------------- | | for Effective Bandwidth Utilisation / |/ [_ [_ |) |_| N E T W O R K S | +=========================================================================*/
