I also get the "bad crc" messages, mainly on inbound transfers (I think), but the card keeps working. On the first large outbound transfer after reboot, I always get the following messages: de1: abnormal interrupt: transmit underflow (raising TX threshold to 96|256) de1: abnormal interrupt: transmit underflow (raising TX threshold to 1024) de1: abnormal interrupt: transmit underflow (switching to store-and-forward mode) Also, the outbound transfer rate seems to have decreased from 6.5-7.5MB/s to 2.5-4.5MB/s, but I am still not sure whether this is caused by the changes in de driver, or the changes in the SMP kernel. Inbound transfers are still at the rate of 6.5-7.5MB/s. Nishio Shuichi
