Hello.

I have taken a look at your problem on weekends.

Please, apply the attached patch to reiser4progs-1.0.7,
and check your partition again. The patched fsck after
check phase should report about minor corruption and
suggest to repair it with --fix option.

Please, report about results.

Thanks,
Edward.
