Did you ever get this behavior using something other than busybox?

I guess this is a problem with busybox.  I have know that Petitboot has
a similar, and I think the same, problem for a long time.  Often telnet
sessions will just stop working.  I tried to debug it before, but could
never find the trouble.

Please check if you get the same behavior with this test:

1) Install http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-petitboot/ps3-petitboot-09.06.09.bld
2) Boot PS3 into petitboot and then exit to shell
3) Run your udp-stress.c test program from a host PC
(PS3 networking hangs up)
4) Ping host PC from PS3
(PS3 now works OK)
