64bit and 32bit DMA don't have anything to do with the CPU. It's about the bus. 64bit DMA is only used for the PCI-E bus. 32bit DMA is correct for your machine and card. > ifconfig wlan0 up had to be called multiple times (the first once or > twice it would give a Protocol Error, but then on the 2nd/3rd it would > load). The moment I hit enter on iwlist scan, I'd get a kernel panic. Can you please give more kernel messages about this "Protocol Error"? > Details: > AMD64, 1.2GB RAM > bcm4306 rev03 I don't think this cards supports the address extension bits. (Which you actually need to get this working). But I can write some patch that checks the hardware if it supports this or not. > firmware taken from http://svit.epfl.ch/stuff/wl_apsta.o > > If there's still a chance my card may support the extra addressing, > I'd be more than happy to provide whatever info is needed.

I would say such a nonsense is common practice for vendors ;) -- Greetings Michael. _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
