Yes, that's what I said. If you start the httpd example and if you just 
request some http data while running your pings, it doesn't crash. If 
you don't request tcp or udp data, it crashes immediately.

I have to check with my EIR if it crashes too if it just boots up an did 
not get any data from radio stations before.
Then it is a problem in the stack and not the emac. But there was a 
problem reported that seems to be in the same corner. It was said, that 
lowering the tcp threads priority below the emac threads priority acts 
as a workaround.

Nevertheless I try to find the bug and fix it. But I was starting on the 
PHY side of the at91_emac code and it doesn't make sense to leave 
everything and start on the other side again. But I try my very best.

If someone else starts some deeper investigation please contact me 
and/or keep us up to date.

Best regards
Ulrich
