Jarek, Following your indications I did it both ways ! Without commit 30902dc3cb0ea1cfc7ac2b17bcf478ff98420d74 patch kernel-2.6.27-rc7 is no longer subject to kernel panic when running ROSE applications. Reversely, when this patch is applied to rose-patched 2.6.25.10 kernel, this one reboots a few seconds after ROSE application are started. Otherwise it is very stable. I checked about three times this behaviour for both kernels with and without the incriminated patch. This confirms without doubt that it is responsible of observed kernel panic. Is there however a possibility to find a solution to cure the problem this patch was dedicated to ?

With kernel-2.6.27-rc7 and ypur patches including netrom one I observed three events via netconsole. I think that they were triggered by NetRom activity I exercized on purpose. See attached documents.

More precisely: I'd like to finish the main problem (oops) in this thread before trying possibly new things in NetRom etc., so it would be nice if you could acknowledge to David that reverting his patch fixes this for sure. Additionally it would be nice to check this Tihomir Heidelberg's fix as an alternative.

Jarek, Yes, previous reports were without reverting David's patch. Now I have removed David's patch (ax25_std_timer.c) and reverted 9A4GL patch (af_ax25.c). Thus present kernel is the original plus 9A4GL patch plus your AX25_DBG and netrom patches and minus David's patch. The system has been stable for two hours and there is nothing special in /var/log/messages as can be seen the sample below.

Great! So, I think we could agree with this: 1. Reverting this patch fixes the oops which started this thread: commit 30902dc3cb0ea1cfc7ac2b17bcf478ff98420d74 Author: David S. Miller <davem@davemloft.net> Date: Tue Jun 17 21:26:37 2008 -0700 ax25: Fix std timer socket destroy handling. 2. Alternative (original) fix proposed by Tihomir Hidelberg: http://marc.info/?l=linux-netdev&m=121370472223572&w=2 doesn't seem to cause any problems. David, please reconsider these changes as reported and tested by Bernard. Bernard, It looks like my netrom patch removes these unorphaned sockets from this debugging log, so I'll resend this signed off soon. Since now, please, treat these 1. & 2. above plus lib8390 & netrom patches as a base for next tests, and if there are again any new bugs from new tests, start new threads for them.
