RE: kmalloc error when receiving a packet.

Karl, Thanks for the reply, I followed the ax25-howto letter for letter,
patched recompiled my 2.0.33 kernel, recompiled ax25-utils-2.1.42a-glibc,
and got the same kmalloc errors.
I tried it with a 2.0.35 kernel and it ran for a little while, then I was
doing a ping test, the pinged station did an ARP request, my machine sent
ARP response, then it stopped transmitting data to the tty port. The pings
were going according to LISTEN, but nothing was getting to the tnc. I
rebooted the machine, and now I get the kmalloc errors again.
Could there posibally be a problem or interaction with the kernel's
digiboard driver?

Thanks for any help.

Hi Jason, reboot the computer and as root type ifconfig <enter> and see if
ax0 is loaded. If not then there is something wrong with the startup file
or the ax25-util compiled binary files are not being called properly.

Please read the ax25-HOWTO again and run with care the tests that Terry
has in it.
