Ok, looks really like a driver/hardware issue. > > That looks as if no data is in the socket queue. > In addition to that I also read in directly the status register from the > rt_eepro100. > I.e.

According to the 8255x manual (page 35/36), this is an impossible value. The lowest 2 bits should be 0, and when the succeeding two bits are both 1 like here, this means a "reserved" state. Just to cross-check: how do normal status value look like for you? > And this value looks fairly strange to me. > If I understand the driver, this value indicates that a packet has > been received or there was an rx error as (status & 0x5000) is not zero. > The question is: Why can I get this status value but not being in the > interrupt routine?!? Don't know yet, maybe some "errata" of your chip revision that is not caught by the eepro100. What is your revision by the way? We are mostly on 8 or 9 here. Jan
