Strange behavior is not it ;-)

I have seen this before and it was due to a bad timing setup of the
dm9000 chip select.

-	at91_sys_write(AT91_SMC_CYCLE(2), AT91_SMC_NWECYCLE_(0) | AT91_SMC_NRDCYCLE_(16));
+	at91_sys_write(AT91_SMC_CYCLE(2), AT91_SMC_NWECYCLE_(16) | AT91_SMC_NRDCYCLE_(16));

Is you have the first configuration, try with the second and it should
fix your problem.

Hope that it helps. Tell us if it works.
