From mboxrd@z Thu Jan 1 00:00:00 1970 From: Julian Somers Date: Sun, 29 May 2005 21:19:44 +0000 Subject: No incoming data: GPRS, kernel 2.6.9, ppp 2.4.2 Message-Id: <20050529211944.GE2052@dev.wiredocean.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ppp@vger.kernel.org Hi I have a problem using Ericsson phones (T39M and F251M) for GPRS with pppd 2.4.2 and kernel 2.6.9. The connection seems to go through fine. I can send any amount of outgoing data. But I never get more than 3 or 4 packets of incoming data. About 3 times out of 10 the connection works perfectly, and stays connected indefinitely. I can see no difference in the logs between successful connections and unsuccessful connections, except for this lack of incoming data. I can use GPRS on several other phones with no problems. I can use these Ericsson phones for GPRS on a machine running kernel 2.4.26, with the identical pppd binary, config files and chat script copied across. Is there any known problem with ppp 2.4.2 and kernel 2.6.9? Any clues as to what might cause intermittent one-way connecitons?
