Same thing on a Core 2 running Feisty AMD64, w/ 2GB of RAM. I compressed a .iso with create_compressed_fs -L -1 -B $((4*1024*1024)) -v foo.iso foo.iso.cloop modprobe cloop file="$PWD/foo.iso.cloop"
and then my kernel oopsed with very similar, but not identical addresses to the bug submitter's oops.
