Heh... I'm thinking more people need to copy 170 meg files around :)
Anyway, new oops trying to move the file across file systems. Same oops occurs when I try to copy the file across file systems.
Kernel messages are...
03:01: rw=0, want=2004318072, limit=1799248 attempt to access beyond end of device 03:01: rw=0, want=2004318072, limit=1799248 kernel BUG at buffer.c:1236!
Oops and running through ksymsoops gives
