I also tried removing the USB bits from if_ndis.ko and ndis.ko, but that didn't change the situation. *) ACPI power off won't work if the ndis0 interface is up, the shutdown process hangs after the final "Uptime: ..." output. If I then push the power button, I get an "acpi: suspend request ignored (not ready yet)" message. Note that this _only_ happens if ndis0 is up. If the interface is down the machine powers off as expected. I'm using a IBM Thinkpad T42p with the latest .sys and .inf from the IBM website, the card is an Intel PRO/Wireless 2100. cheers, le -- Lukas Ertl http://homepage.univie.ac.at/l.ertl/ le@FreeBSD.org http://people.freebsd.org/~le/
