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.

Wolfgang
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).
