SubjectRe: Lockups on 2.0.15-2.0.18
 Alan Cox posted a patch against 2.0.17 that was supposed to fix some SMP 
problems.. I just tried 2.0.18 thinking it would be correted there but I
was wrong. Time to try the patch I guess. I have the same symtoms..
kernels less than 2.0.15 work with SMP new ones do not. i'll forward you
the post alan made..
