    Looking at the trace, disabling of IRQ is probably caused by something 
other than RX FIFO overflow (when it caused disabling IRQ, there were no error 
messages printed because RFE interrupt went completely unhandled). Probably 
there's more interrupt mask issues lurking in the driver...

    No idea. I still don't have access to Lager and on BOCK-W we have no 
issues with NFS. What are your symptoms?

WBR, Sergei
