I was trying to test tg3 w/ and w/o TSO on bcm5701 NICs...wasn't
getting good results with anything (260-380Mb/s on TCP stream).
I switched netperf "client" from a500 (2.4 kernel, gsyprf11) to
ia64 machine ("iota") also running 2.6.0-test9. The netperf "server"
(a500 running 2.6.0-t9, "ion") data page faulted. It seemed to be
working until I tried to run top...then started spewing:
kernel BUG at fs/proc/base.c:746!
before it panic'd.
It's past 1AM...I can post more details tomorrow or later this
week. I have matching kernel/source on ion:/usr/src/linux-2.6.
Here's the console output.
hth,
