My machine at work (AMD1700+) has same problems - here is it's dmesg IRQs: [jakobbg@nusse ~]$ dmesg | grep -i irq ioapic0 <Version 0.3> irqs 0-23 on motherboard rl0: <Accton MPX 5030/5038 10/100BaseTX> port 0xec00-0xecff mem 0xdfffff00-= 0xdfffffff irq 19 at device 8.0 on pci0 uhci0: <VIA 83C572 USB controller> port 0xe000-0xe01f irq 21 at device 16.0= on pci0 uhci1: <VIA 83C572 USB controller> port 0xe400-0xe41f irq 21 at device 16.1= on pci0 uhci2: <VIA 83C572 USB controller> port 0xe800-0xe81f irq 21 at device 16.2= on pci0 pcm0: <VIA VT8235> port 0xdc00-0xdcff irq 22 at device 17.5 on pci0 atkbd0: <AT Keyboard> irq 1 on atkbdc0 psm0: <PS/2 Mouse> irq 12 on atkbdc0 fdc0: <Enhanced floppy controller> at port 0x3f0-0x3f5 irq 6 drq 2 on isa0 unknown: <PNP0f13> can't assign resources (irq) drm0: <Matrox G550 (AGP)> mem 0xdf000000-0xdf7fffff,0xdfefc000-0xdfefffff,0= xdc000000-0xddffffff irq 16 at device 0.0 on pci1 While doing this: $ cd /tmp && tar jxf /usr/ports/distfiles/openoffice.org2.0/OOo_1.9m130_source.tar.bz2=20 During it's entire run I ran this as well (my computer did nothing else during that time): while(true); do date >> vmstat.log && vmstat -i >> vmstat.log && sleep 1; d= one The logfile can be found at <http://www.grimstveit.no/jakob/files/temp/vmstat.log>.
