Hello!

Если у меня 2.4.20-alt8 скомпилировалось так же, то упало вот здесь
(include/linux/sched.h):

#define is_dumpable(tsk)        ((tsk)->task_dumpable && (tsk)->mm->dumpable)

поскольку (tsk)->mm оказался NULL.

В 2.4.21 здесь написано:

#define is_dumpable(tsk)    ((tsk)->task_dumpable && (tsk)->mm && (tsk)->mm->dumpable)

При неудачном запуске ps в сислог пишется следущее:
