Hi Neil, Can you provide me details of your setup? Is there any kernel configuration that I will have to change and build my kernel with that?

If I do exactly the same sequence it works perfectly. So there must be some important different between your setup and mine. - What happens if you leave off the "--bitmap=/tmp/bitmap.txt --bitmap-chunk=1024" Does it then work? - What filesystem is on /tmp - Can you give me complete /var/log/messages from before you create the array until this error?
