Subject: Re: ax25 rose Re: kernel panic linux-2.6.27-rc7

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.
