general protection fault when copying a lot file from windows to ubuntu (samba)

[Martijn Brinkers]

Hi,

My system always crashes with a general protection fault when I copy a
lot of files from Windows XP to my Ubuntu over Samba. Small number of
files seems to work but when I copy a large number of files my system
crashes on a general protection fault.

uname -a: 

Linux ubuntu 2.6.20-16-generic #2 SMP Sun Sep 23 18:31:23 UTC 2007
x86_64 GNU/Linux

CPU: Intel(R) Core(TM)2 Quad CPU

any idea what's causing this?

Martijn
