Comment 27 for bug 183303

Bad news - just fired up Intrepid Alpha 5 and couldn't create an AdHoc network - it goes well up until stage 5 (iptables are even modified by this point) and then fails with the following syslog messages:

Sep 18 11:52:06 ubuntu NetworkManager: <WARN> nm_device_activate_stage5_ip_config_commit(): Activation (wlan0) Stage 5 of 5 (IP Configure Commit) start sharing failed.

Is this attached syslog output enough for the kernel / mac80211 devs to take a deeper look at this problem?

Please tell me what more we can supply to help solving this bug.
