The 'mismatched read page pointers' I've seen on the EtherNEC 8390 based card
as well, it seems to indicate that the receive buffer overruns. I'm using a
timer interrupt there, so that is expected to happen.
Might 'trigger send called with tx busy' also indicate a failure to receive the
txdone interrupt? Maybe you're not getting any interrupts from the card? What
does /proc/interrupts register regarding the 8390 driver?
