It seems to me the cause of the tx timeouts is the "HostError", which is a PCI bus error. This most likely caused the adapter to hang and then the transmits started timing out. As far as I can tell, the dl2k driver code is common between 2.4 and 2.6. So, some other change in the kernel is causing the driver to behave differently and expose this problem. I am not the maintainer, but I can try to assist you. However, it will require running debug drivers (as I am not able to find any documentation on this adapter). If you are not willing or able to do this, then I would suggest going back to the 2.4 kernel.
