Thanks for the update.

Still I'm seeing reproducable hangs with this version of sky2 (as reported in 
bugzilla 6084 and discussed on netdev).

Stephen, if there is anything I can do to narrow down my hangs a bit more 
systematically, please let me know, I'd be happy to help.

There is an outstanding bug where the sky2 will hang if it receives a 
packet larger than the
MTU.  At this point, there isn't enough information on chip behavior to fix.

You could try using a larger mut or patching the driver so that the 
rx_buffer_size is always big (like 4k).
