I am now having the same problems on my laptop that I experience when
using the netdev kernels.  My prism54 wireless card won't get a dhcp
address using NetworkManager.  If I manually ifup the wireless interface
it does work properly.  How  would you like bug reports for this kernel
put into bugzilla?


This might be more of a NetworkManager issue  or timing problem. I
have the same problem with the current rawhide on a couple of
different laptops that are using the ipw2x00 drivers.
