I gave it a try on my IBM thinkpad booted in docking station which has an ACPIPHP slot. An echo 0 > /sys/bus/pci/slots/SOME_NUMBER/power is removing some devices ( verified with cat /proc/pci ), but gives some kernel errors on console. An echo 1 > /sys/bus/pci/slots/SOME_NUMBER/power is not activating the devices again ( again tested with cat /proc/pci) but gives some kernel errors on console + some cpu registers and a segfault. In my dock I have a ide controller, 2 yenta pcmcia slots, and a PCI slot where I have a bttv supported tv card. All drivers needed were compiled in kernel, no modules needed. Was this setup supposed to work ? I can provide more info if needed. Thanks, Paul __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
