When loading if_wpi I get the following line saying that "bus_dmamem_alloc failed to align memory properly"

wpi0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54

Therefore I'm unable to make wpi0 work at all.

Could you please tell me what should I do?

Ciao, Vittorio

The bus_dmamem_alloc message is harmless in your case. Due to limitations in the freebsd allocator, sometimes requesting a 16k aligned block of dma memory fails. As a temporary work around the wpi driver reattempts the allocation. If it truely does fail you'll not get a wpi0 device showing up, which clearly you did :).

These warning messages will go away when I sync the next lot of updates to the driver which aren't quite ready yet.

Can you describe a little more what you mean by wpi doesn't work?
