pfSense

Hi

After a fresh and successful installation on my soekris net6501 on the internal harddrive, pfSense won't boot.
The Installer walks trough the setup without any complications, but after a reboot, the machine is unable to boot from the harddrive and keeps rebooting forever. no error message what so ever.

And btw, after that i found A suggestion on the Internet that I should try and install an older version of pfSense (I took 2.1.3) and upgrade later, witch bypasses the problem.
BUT this woun't work either...
With that the installer doesnt even show up.

It stopps at the following part

...

and then remove invalid mount options from /etc/fstab.

Loader variables:
vfs.root.mountfrom=ufs:/dev/ufs/pfsense0
vfs.root.mountfrom.options=ro,sync,noatime

Manual root filesystem specification:
  <fstype>:<device>  Mount <device> using filesystem <fstype>
                       eg. ufs:/dev/da0s1a
                       eg. cd9660:/dev/acd0
                       This is equivalent to: mount -t cd9660 /dev/acd0 /

  ?                  List valid disk boot devices
  <empty line>       Abort manual input

mountroot>

Any ideas on how to fix this?

best regards
