Hi Jan, I have actually identified the difference and made a patch against the rt_eepro100.c. Using this patch my setup is running fine now!!!! I do not understand in detail what is happening as it seems to be important to read the status register more than once under some circumstances... Anyway, enclosed is the patch. Perhaps as many people as possible can test it and see if there are some issues that came in by this patch.
