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?
