I use 2.4.19 with Debian unstable and got it nicely up and running with
a Yam modem at 9k6. Then I tried the INP3 patch by pe1rqx, verson 004
and the kernel goes down as soon as I try to do an actual call on the radio port.
It also seems like something goes wrong as soon as I load YAM module
The kernel reports: segmentation fault, at each call to ifconfig. The log
shows (i removed the timestamps):

I was thinking of giving up and do without INP3, but if anyone knows this problem and
perhaps a hint where to look?? I used the patch which was meant for a 2.4.19 prerelease, but
agains the official 2.4.19 kernel source. I cant find any other info on this than:
http://sharon.pi8zaa.ampr.org/users/pe1rxq/inp3.html
Btw. What is the "sock_orphan patch"?

Its a fix for a prblem with earlier 2.4 kernels that would crash as almost
immediatly.
I haven't tried the patch on a 'real' 2.4.19 source yet so it could be the
cause...
But ax25 in 2.4 is terribly broken :(
On a side note does anybody know how the status of ax25 in 2.5 is?
I know there have been some changes, but I don't get replies from any mails
to the author....
I just want to know if it is just as likely to crash as 2.4, more likely or
is it getting better?
In other words is it worth to try??? What needs to be done? Can I help???

Thanks for the response. I just booted a new kernel (2.4.20),
with Yam and INP3 patch and it seems to be working well now,
except that the patched nrattach does not seem to find the nrports file.
I'll sort it out soon.
Riley Williams suggested to try the 2.4.20 and there are some
fixes to the Yam driver. I guess I might also have confused the
system by not actually booting the modified kernel, just replacing
the modules. I suspect there was a little problem in the Yam code.
Well, 2.4.20 seems to be ok.
It would be nice if we could improve the kernel AX.25 support. You
and others has made some nice patches which could perhaps be
included into the mainstream kernel??

It probably looking in /usr/local/etc/ax25 instead of /etc/ax25 or vice
versa.
You can set it with configure before compiling.
(Or make one a symlink to the other like I did to prevent future mistakes
:)
