Debug logging shows that it's correctly recognising the connection as 10Mbit, half duplex. The port is unusable like this (despite the odd packet or two). If I connect a 100Mbit back-to-back with another adaptec, or connect myself to the same 10Mbit port as before through a 100Mbit switch (giving me a 100Mbit local connection) it works fine. A tulip board to the same port (direct @ 10Mbit) also works fine. Anyone else seen anything like this? Couldn't see anything in the archives. Thanks, Martin. PS. Linux 2.4.6 kernel.
