AMD64 gentoo 2008 booting error [solved]

[DeIM]

Hi, I have just intalled gentoo 2008 AMD64 on my Athlon 64 X2 5000+.
After reboot it writes
----
* Mounting proc at /proc ... [ ok ]
* Mounting sysfs at /sys ... [ ok ]
* Mounting /dev for udev ... [ oops ]

* The "mount" command failed with error:

--I have czech interface so there is something like (translated):
incorrect type SS, incorrect switch, incorrect superblock on udev
or code page is missing or other error
in some cases information can be found in system protocol try dmesg | tail for example

* Since this is a critical task, startup cannot continue
----

I have SATA disk
my /etc/fstab:
/dev/sda3 / raiserfs noatime,notail 0 1
/dev/sda4 none swap sw 0 0

thanks in advance

reinstalling udev solved my problem
