Re: Driver for DWL-G122 rev C1 Octavian Ionescu Tue Dec 16 00:00:42 2008 

hi,
i have recompiled and everything have worked very good :) now i am able to use my notebook without having to stay just at my desk :)
btw where i cad read a little more about those dependencies like SMP enabled -> have to use usb2.
i have searched on google about how to enable usb2 on the kernel but i found just exemples of kernel config's and not why it shoul dbe used. 


Thank you,

Let me guess you have SMP machine with SMP enabled kernel?
In that case usb ehci have some bugs triggered with rum driver.

Workaround: disable smp:
# echo "kern.smp.disabled=1" >> /boot/loader.conf and reboot.

Fix:
use if_rum2 from usb2:

# echo "usb2_wlan_rum_load=YES" >> /boot/loader.conf

For this one to really work you need first to remove usb,uhci,ehci,ohci and
others old usb stuff from kernel conf, and use usb2 as modules ...
