>Description:
my fresh installed 6.1-RELEASE workstation doesn't survive to a simple fork bomb. after launching the bomb, it freezes a few seconds and then my computer reboots. afair, 5.4 systems survived it.
i didn't tweak my kernel, i just use home compiled GENERIC without overriden CFLAGS. everything is almost default install. what about adding a forkbomb in regression tests ?
>How-To-Repeat:
echo 'int main() { for(;;) fork(); }' | gcc -x c - && ./a.out
>Fix:
i don't know how to fix it. it looks like a scheduler issue.
