Ok here I noticed when I boot with the new Xen kernel then lspci -vnn
shows module ssb loaded
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312
802.11b/g [14e4:4315] (rev 01)

which is not the correct thing as in an old kernel (which was by
default installed when I installed Ubuntu 10.04) I see

Kernel driver in use: wl
Kernel modules: wl, ssb
So I think this is the source of my problem but in the new kernel when
I boot with Xen kernel which shows
only
Kernel modules: ssb
how do I bring these options in newly compiled kernel as in the
correct kernel it shows in last two lines
Kernel driver in use: wl
Kernel modules: wl, ssb
