Message-ID: <200311092245.06049.nardin@inf.ufsc.br> (raw)
* With MTU 1500, 'ping -s $SIZE anotherhost' doesn' t work for $SIZE >= 1472,
up to 1471 works. With MTU <= 1499 everything seems ok.
* modprobe -r forcedeth segfaults/oopses.
Here's what I got in kern.log (using 2.6.0-test9 + Nick Piggin's scheduler v17a,
forcedeth 0.14 from akpm's patches (debug disabled, sorry)):
