Please, can you explain, why similar board from PCEngines (Alix 2D13)
with same software (OpenWRT image) just works, but Soekris board shows
some unstability?

Attila,
Thank you for the detailed post. It is clear that you have some
understanding of best practices regarding digital PCB layout. However,
you've made a number of assumptions and generalizations. Are you
certain that there are no power and ground layers within the net5501

Attila,
You claim to have solved a mystery but you did not provide any
technical details of the problem or the solution. This is a support
list but instead of being supportive or asking for support, you are
being critical of a product that most users do not have any trouble

Moin,
Some might remember that i talked a few times about crashes of my
net5501 under heavy load or when using wlan. Eg when i switched
wlan on and did generate some traffic it didn't take more than 5 minutes
to crash the net5501.
I finaly got the time to work on this again and got my net5501
