I have tried momentarily interrupting the connection BSC<->BTS with iptables but I cannot as yet provoke the event that causes this.. ah just now it happens again (meanwhile I am watching a straight ping to the bts (for what it's worth) and I see nothing unusual there. Maybe this actually has not got to do with the wifi link after all, and that is just coincidence? <0004> abis_rsl.c:717 (bts=0,trx=0,ts=1,ss=0) RF CHANNEL RELEASE ACK <0004> abis_rsl.c:735 (bts=0,trx=0,ts=1,ss=0) CHAN REL ACK for broken channel.
