Hi,
This is still happening. I ran the same set of tests on a totally
different network, with my xircom realport ethernet card (tulip
driver - 16bit) and from linux to linux and windows to linux. Scrolling
through a message in mutt eventually slows down and if I lift my finger
off the enter key whilst it's slow the scrolling keeps going, as if it
was all bufferd. If I do a pingflood (ping -f) from a machine to my
laptop it's all fine.
I am also now running 2.6.9-rc1-mm4.
