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: ====================================================== commit 59fe3ee33bdb7e8dd0584271382fb94880f68002 Author: Johannes Berg Date: Sat Mar 21 17:08:43 2009 +0100 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. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville ============================================================ 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.
