I can reproduce this by wget'ing a 5.xGB file from my MythTV box.
The receiving end is a Fedora 9, AMD x86_64 box with an Abit m56s-s3
board using nVidia Corporation MCP65 Ethernet (rev a3).
It uses the forcedeth: Reverse Engineered nForce ethernet driver.
Version 0.61.

Should I forward this info to someone so this could be fixed?
Someone doing the kernel memory management?
Or forcedeth?
Or?

Please let me know.

Thanks,
Udo
