Hi,

well, it turned out it is not a libc issue but indeed a kernel issue.
The reason is, that accept4 is not available on arm with 2.6.32.
It was only introduced for 2.6.36 - see this commit:

21d93e2e29722d7832f61cc56d73fb953ee6578e

I applied this simple patch to my kernel 2.6.32, rebuild and voila! everything
works as expected :)

So since version 168 udev requires more than 2.6.32 - 2.6.36 to be precise,
because of the accept4 call.

Couldnt you just use the old accept instead so that udev also works with 2.6.32
non-x86 systems? But it would probably be simpler to just raise the kernel
requirements for udev from .32 to .36.

I'm very happy this is solved now :)

cheers, josch
