We had the same problem ...
It was caused by buggy memory (It was set to turbo, but then there were
So, we had the respawning with tty6-error, but after one MKDEV it was fixed
So I know this won't help you, but it was the experience we made ...
PS: What about a /etc/init.d/mymakedevs.sh-Skript, which recreates them every
boot ... ?!
