un-removable files on reiserfs

i have a few files on a reiserfs disk that i cannot remove. they showed
up sometime after i started using 2.4.17.  also, i haven't been able to
find an oops in my ksymoops logs.

i also have used 2.4.18 and 2.4.19-pre2 for a day or two each.

here is an example: /non-debian/src/openbsd/sys/arch/sun3/stand/CVS/nn

% ls -l /non-debian/src/openbsd/sys/arch/sun3/stand/CVS
ls: /non-debian/src/openbsd/sys/arch/sun3/stand/CVS/nn: No such file or directory
total 8
-rw-r--r--    1 rob      rob           211 Oct 17  2001 Entries
-rw-r--r--    1 rob      rob            24 Oct 17  2001 Repository

% ls -l /non-debian/src/openbsd/sys/arch/sun3/stand/CVS/nn
ls: /non-debian/src/openbsd/sys/arch/sun3/stand/CVS/nn: No such file or directory

% ls -ld /non-debian/src/openbsd/sys/arch/sun3/stand/CVS
drwxr-xr-x    2 rob      rob           104 Oct 19  2001 /non-debian/src/openbsd/sys/arch/sun3/stand/CVS

i can provide any other info, if needed.

thanks.
rob.
