I'm experiencing something like this too. I can confirm it for at least since
2.6.12. My current System is Ubuntu Dapper Drake. Whenever I copy a
reasonably large file (> 150 MB) from my box to a WinXp SP2 box my system
first gets very large latencies going up to 5 seconds. After nearly a minute
of copying it will freeze completely. No Numlock no SysRq working anymore.
No output in dmesg at all. It just starts getting slower with high latencies
and will freeze completely if you not kill -9 the cp process. This so far has
only happened to me on outbound copying. (E.g. cp a local file to remote)
host. Inbound (WinXP to my Linux box) works flawlessly.
Some more Info:
cp process hangs with status D in wchan SendRe...
kill -9 not working unless you delete the file on the remote site. Then cp
exits as it should
