2.6.15 ax25 system lockup with kissattach

[Mike McCarthy, W1NR]

I am using SuSE 10.0 with 2.6.15 kernel built from source or via SuSE kotd
rpm.  The system will hang when issuing kissattach command.

Following is a trace of commands issued:


>worf:~ # modprobe -v mkiss
>insmod /lib/modules/2.6.15-20060103193109-debug/kernel/lib/crc16.ko
>insmod /lib/modules/2.6.15-20060103193109-debug/kernel/net/ax25/ax25.ko

>AX.25 port 2m bound to device ax0


That's all folks.  System locked up hard.  Caps lock and scroll lock lights
flashing.  System needs a hard reset.

2.6.14-5 appears to be fine.  Tried recompiled tools and libraries as well.
Others report similar problems on Debian systems with 2.6.15 kernel as well.
