 Testsuites vary between packages, and are often very hard to debug.
I'm not sure about your distinction between errors and failures - a status
of 0 is a successful test, everything else failed (in some packages, some
failures are 'expected').  My own view is that status >= 127 often means
a program is missing.

 In this case, the "meat" of the test is in tests/r_move_itable/script, but

The "bad magic number" message is EXT2_ET_BAD_MAGIC in
./lib/ext2fs/ext2_err.et.in and is probably called from lib/ext2fs/openfs.c
in ext2fs_open2.  But as to why it would fail, I've no idea.

If in doubt, I normally blame virtual machines :)  But in this case, I
wonder if you have managed to mount /mnt/lfs with excessive
restrictions (perhaps 'nodev') ?
