hi

When downloading/streaming high amounts of data (over HTTP), Linux 
2.4.20-pre10 hangs. And it really hangs. alt+sysrq (from usb keyboard) 
doesn't work... The problem is easily reproducable by just doing a wget 
http://something/largefile (interface used is PCI ID 01:02.0)

the problem does not occur when streaming over the Intel gigE interface.
