Hello, This is with FreeBSD 5.4-REL on a Fujitsu-Siemens notebook, type Amilo. Without inserting or using any PCMCIA card from time ti time I see an increasing temperature of the CPU (this was the only reason why I noted it at all) and top shows: CPU states: 0.8% user, 0.0% nice, 0.4% system, 22.9% interrupt, 76.0% idle The high rate of interrupts are coming from cardbus somehow: $ vmstat -i interrupt total rate irq0: clk 1526386 99 irq1: atkbd0 19720 1 irq4: sio0 2 0 irq6: fdc0 10 0 irq7: 3 0 stray irq7 3 0 irq8: rtc 1953511 127 irq9: acpi0 1102 0 irq11: cbb1 pcm0++* 126785936 8304 <*********** irq12: psm0 116294 7 irq14: ata0 70657 4 irq15: ata1 33673 2 Total 130507297 8548 Some more infos from sysctl: $ sysctl -a | fgrep cbb hw.cbb.start_memory: 2281701376 hw.cbb.start_16_io: 256 hw.cbb.start_32_io: 4096 hw.cbb.debug: 0 dev.cbb.0.%desc: ENE CB1420 PCI-CardBus Bridge dev.cbb.0.%driver: cbb dev.cbb.0.%location: slot=9 function=0 handle=\_SB_.PCI0.CRD0 dev.cbb.0.%pnpinfo: vendor=0x1524 device=0x1420 subvendor=0x17c0 subdevice=0x320 2 class=0x060700 dev.cbb.0.%parent: pci0 dev.cbb.1.%desc: ENE CB1420 PCI-CardBus Bridge dev.cbb.1.%driver: cbb dev.cbb.1.%location: slot=9 function=1 handle=\_SB_.PCI0.CRD1 dev.cbb.1.%pnpinfo: vendor=0x1524 device=0x1420 subvendor=0x17c0 subdevice=0x320 2 class=0x060700 dev.cbb.1.%parent: pci0 dev.cardbus.0.%parent: cbb0 dev.cardbus.1.%parent: cbb1 dev.pccard.0.%parent: cbb0 dev.pccard.1.%parent: cbb1 $ sysctl -a | fgrep pcm hw.snd.pcm0.buffersize: 16384 hw.snd.pcm0.vchans: 4 hw.snd.pcm0.ac97rate: 48000 dev.pcm.0.%desc: SiS 7012 dev.pcm.0.%driver: pcm dev.pcm.0.%location: slot=2 function=7 dev.pcm.0.%pnpinfo: vendor=0x1039 device=0x7012 subvendor=0x17c0 subdevice=0x200 0 class=0x040100 dev.pcm.0.%parent: pci0 What can I do? matthias -- Matthias Apitz / Sisis Informationssysteme GmbH Gruenwalder Weg 28g / D-82041 Oberhaching Fon: ++49 89 / 61308-351, Fax: -399, Mobile ++49 170 4527211 http://www.sisis.de/
