Hello Jean-Paul, Van: "Jean-Paul ROUBELAT" <jpr@f6fbb.org>

Did you try the 2.2.19 kernel distributed in 7.3 ?

I overlooked that one! I was already thinking about downgrading to a 2.2.x kernel but did not realized one was packaged in the distribution. Anyway, I loaded this kernel and it seems to work fine so far. Given that with FBB the Linux almost crashed at instant (just after FBB sended its beacons - I put trace info in FBB's drv_sock.c to see if it crashed at a specific operation) and now it runs at least 30 minutes. I think the problem is realy in the AX.25 support of the new 2.4.x kernel. In the meantime I also found out that other AX.25 packages fail as well. I have a small program to do reverse-forwarding (connection to the local BBS and then fetching the articles lzhuf compressed and putting them in the FBB's mail.in. This way the local BBS does not need forwarding rules setup for me, I just pull it). Anyway, this program could run for a while but then also ended up in the lockup I described. Thanks for this suggestion, at least now I have something that runs until the 2.4.x kernel is fixed. Kind regards, Henk.
