Here, it doesn't fix 
http://marc.info/?l=linux-kernel&m=125382651922142&w=2

But I found something in syslog:

Sep 25 16:17:31 pervalidus agetty[1465]: /dev/tty2: No such file or directory
Sep 25 16:17:31 pervalidus agetty[1464]: /dev/tty1: No such file or directory
Sep 25 16:17:31 pervalidus agetty[1466]: /dev/tty3: No such file or directory
...

So, why it works with 2.6.30.7 and not 2.6.30.1 ?

And I also noticed that it takes longer with 2.6.30.7 than 
before for the login and password prompts to appear.

In /etc/inittab, I have

c1:1235:respawn:/sbin/agetty 38400 tty1 linux
c2:1235:respawn:/sbin/agetty 38400 tty2 linux
c3:1235:respawn:/sbin/agetty 38400 tty3 linux
c4:1235:respawn:/sbin/agetty 38400 vc/4 linux (yes, nothing 
about vc/4 in the logs)

So, with 2.6.30, udev doesn't create the symlinks from vc/*, or 
it's something in the kernel that prevents it ?
