Hello

I have always used vanilla kernel with very old patch for ATM
(name: linux-2.3.99-pre6-fore200e-0.2f.patch) It worked well -
trouble-free. 
I have just tried vanilla 2.4.22, here is oops. ATM doesn't work :(

ksymoops 2.4.5 on i686 2.4.22.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.22/ (default)
     -m /lib/modules/2.4.22/System.map (specified)
