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)
