My kernel configuration file contains: % device cbb % device pccard % device cardbus (BTW, can someone explain me what are the purpose of those devices ? I can't really understand it from the manpage.) Output from pciconf(8): % cbb0@pci6:1:0: class=0x060700 card=0x00661025 chip=0x8031104c rev=0x00 hdr=0x02 % vendor = 'Texas Instruments (TI)' % class = bridge % subclass = PCI-CardBus And the corresponding piece of dmesg: % cbb0: mem 0xc8216000-0xc8216fff irq 10 at device 1.0 on pci6 % cardbus0: on cbb0 % pccard0: <16-bit PCCard bus> on cbb0 vmstat -i: % interrupt total rate % irq0: clk 1094497 998 % irq1: atkbd0 4725 4 % irq8: rtc 140217 127 % irq9: bge0 uhci2+ 59147 53 % irq11: iwi0 uhci0* 6444 5 % irq12: psm0 1719 1 % irq14: ata0 3576 3 % Total 1310325 1195 I tried to turn on debug sysctls, but it shows nothing more: % hw.cardbus.debug: 1 % hw.cardbus.cis_debug: 1 % hw.pccard.debug: 1 % hw.pccard.cis_debug: 1 % hw.cbb.debug: 1 Any help will be welcome. Let me know if you need for informations, such a full verbose dmesg or so. Thank you. Best regards, -- Jeremie Le Hen < jeremie at le-hen dot org >< ttz at chchile dot org >
