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.
