I have just tried the new kernel .... The new kernel is unstable for
me. It hangs very quickly. Most often, it hangs when starting up
wpa_supplicant and gives the following stack trace:

This was using the existing firmware that I had ( from the latest
broadcomm winxp driver from HP's website for my specific model of
notebook ). This firmware never caused a crash on the previous kernel
... so why would it cause one now ?
