It didn't solve. After running 2.6.17.1 for almost 48 hours I already have 4 pppd processes stuck in "ioctl(TIOCSETD..." in the connection finish section. Here's a log of one PPPd process: --- Log --- [...] Jun 29 16:01:36 wifi pppd[18575]: No response to 10 echo-requests Jun 29 16:01:36 wifi pppd[18575]: Serial link appears to be disconnected.

One thing that all pppd processes have in common is that the end peer didn't respond to the our max number of echo-requests.
