Ah, good to know :)

Ah thanks. I just built a new kernel using that patch (i.e. from the
e100-3.0-pm-2-bugfixes branch). I hope that was the right one, the
usrp_e driver looks ok but is only at version 0.2 as opposed to the
one from the e100-3.0-pm-2-fixes-from-review branch which is at
version 0.3. I still get a segfault / kernel NULL pointer dereference
as soon as I modprobe usrp_e though.

cheers
