Description of problem: - Connecting via BlueTooth to my Nokia N70-1 and starting GPRS/EDGE/UMTS internet session with kppp. - When starting ppp session, ppp dies. Trace below. - This worked fine on FC4 with 2.6.14 and some 2.6.15 kernels. Do not work on FC5test2 2.6.15-1.2008_FC5 nor 2.6.15-1.1996_FC5 nor 1955.

Strange, there were no changes between the two builds that could explain this being fixed. If it reappears again, please try to make sure it's on an untainted kernel.
