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?
Cheers,

the line
legal.intel_wpi.license_ack=1
is in /boot/loader.conf
BUT
1)
it seems that sysctl is unable to find it and I have to set it via
kenv legal.intel_wpi.license_ack=1 in a shell.
Shouldn't this variable be set by either sysctl or by loader.conf (that is is
a system variable) OR is it supposed to be set via kenv only?
2)
dhclient is unable to get an IP address (BTW trying to set wpi0 up with a
fixed IP makes wpi0 not associated to any AP)
Here it is a session log

Even giving an ip fixed address to wpi0 doesn't seem to work, - that is - I

Please help

Vittorio,
Do you have a line just like the below in your /etc/rc.conf? I've found
DHCP a little tricky to set up on wireless laptops, and after a Lot of
testing, I got mine to work. (This is getting a dhcp address from a
Linksys router)
ifconfig_wpi0="ssid [your network name] nwkey [your network key] DHCP"
Tim
