Hi, I have this problem as well, and it seems to be some Heisenbug. When I
boot up the computer normaly, udev fails with the already bound socket and I
get no input devices. When I put debug on the kernel command line the problem
seems to get a statistical component, and whenever I put break=init there it
boots as it should (after ctrl-d).
So I put 'ps -A x > /dev/.initramfs/ps-Ax.udev' on the very top of
'/etc/init.t/udev'. Now it seems there are indeed two udevd processes left
[att1] and udev does not start properly.
But when I do 'ps -A x | grep udev > /dev/.initramfs/ps-Ax.udev' there are no
processes left and udev just works.
Summing this up I think it is a timing problem. It seems to me that the udevd
from initramfs is in fact killed, but nobody waits for it to actually die.
For now i do a sleep 1 in /etc/init.d/udev and it seems to work. But I think
this is not a real solution.
Hope this helps,
Matthias
