For older OS'es, you run into this 100% nash/hotplug issue. As a work
around i use a "killall" in the rc.sysvinit script. I'm not sure what
the real bug is, but I guess nash/hotplug are making some invalid assumptions
about the capability of the kernel, and it should just abort instead
of getting into this infinite loop.

Since the fix is easy, I never delved into what it is actually doing. If
there is an interest in fixing this bug, I could investigate.
