INP3 patch + yam = kernel oops

[Øyvind Hanssen]

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:

Btw. What is the "sock_orphan patch"?
