In our last email exchange I got the impression you switch to Intel 
board and did not want to keep replacing cards for testing. Nice to hear 
you have an alternative setup for this and I assume are willing to do 
some testing.

I submitted two patches upstream and additionally I have attached two 
other that are still under review. Could you try these patches and sent 
me the content of the two debugfs files 'macstat' and 'hardware' after a 
stall has occurred.

Arend
