[Soekris] problem with net4801 and 2.5 hdd

[Eduardo Diaz Comellas]

Hi all,

I am facing a problem with some net4801 units and a 2.5 HDD. The disk 
works fine in one of the soekris boxes I've got, but on others it hangs. 
The boot log of a faulty reboot is:

Note the "Pri Mas" tag.

In one of the soekris boxes I've got, it shows the correct model and 
works fine:

Please note that it's the same disk. Only different net4801 motherboards 
(s/n 138142 boots fine, 138408 doesn't).

Is there anyting I can do to solve this issue?
