The problem is more general than rtl8187. The system freezes when I try to
connect with rrtl8187 or b43. Using bisection, the bad commit is as follows:

    mac80211: remove mixed-cell and userspace MLME code

    Neither can currently be set from userspace, so there's no
    regression potential, and neither will be supported from
    userspace since the new userspace APIs allow the SME, which
    is in userspace, to control all we need.

I have not yet tried to see which hunk or hunks cause the proble, but backing
oout that patch allows the system to work correctly.
