isdn4bsd 0.63 was working without a single problem on my setup. When 0.70 came out I immediately upgraded and when 0.70 was integrated into FreeBSD I started using the integrated version. But with 0.70, calls sometimes fail. I have to do "ifconfig isp0 down" and then "ifconfig isp0 up" to get it working again. When it last failed, I caught the following messages in my system log: Jan 31 12:35:09 gold /kernel: i4b: unit 0, assigned TEI = 124 = 0x7c Jan 31 12:35:17 gold /kernel: i4b-L2-i4b_i_frame_queued_up: V(S) == ((V(A) + k) & 127)!

The switch is Siemens EWSD, I'm using a Teles S0/16.3 card, which is connected to a Ascom NT+2ab NT. All of this is running on a AMD5x86 box with a 4.0-CURRENT kernel as of today. It is hard to reproduce this problem, sometimes it doesn't happen for days and sometimes it happens twice in a couple of hours. If I should turn on any other debugging, please tell me. If I don't receive any response, I'll try to enable as much debugging as I can and then send-pr it.
