Following up, I don't think that it is sufficient to treat this chip
as a 5714. I'm doing a buildworld from an NFS mounted /usr/src to a
local /usr/obj while the output is going to my ssh login terminal
window. Every 5 to 7 minutes, I get this in the system log:
Mar 30 15:27:47 neo kernel: nfs server yertle:/usr/src: not responding
Mar 30 15:27:55 neo kernel: bge0: watchdog timeout -- resetting
Mar 30 15:27:55 neo kernel: bge0: link state changed to DOWN
Mar 30 15:27:57 neo kernel: bge0: link state changed to UP
Mar 30 15:27:58 neo kernel: nfs server yertle:/usr/src: is alive again
and it picks up where it left off on the buildworld.
FWIW here is a patch to implement my earlier hack. It obviously
needs someone to go and see how the latest linux kernel supports this
chipset. I've decided to go buy a Sun instead :-)
