    I am glad that your AX25 applications are working fine with Linux kernel
    2.4.x
    I was only reporting that this is not the case when serial link are
    handled by mkiss.
    I assume that it is a question of heavy interrupts load for I have
    traced the problem and found that kernel panics occur very often around
    the same address in ax25 input routines.
    This is probably related to the lot of cli() instructions and the new
    way interrupts are managed in 2.4 kernels.
    All these cli() sti() have been removed in 2.5 kernel. Thats why I hope
    mkiss will work again on 2.6.
