I had a similar predicament when fdisk changed some files to bizarre
character devices. Even '?' showed up in the permissions as well as
the huge group number. I posted a question on comp.os.linux.setup and
got an answer that worked. What has happened is that the inode for
that file (and probably others) has become hopelessly corrupted.
Thankfully, you can delete this.
Boot into single user mode so the fs with this file on it is unmounted
(boot to a root disk if it's on the root partition to make it easier).
# debugfs -w /dev/hda# # check man page to be sure; my notes
# aren't here.
debugfs prompt> clri /path/fstodbdf #clear inode entry for this file
debugfs prompt> rm /path/fstodbdf #remove this offending file
# e2fdsk /dev/hda# # make sure everything's hunky dorry. :)
As always, check over the above with the man pages to be sure I'm not
accidentally giving you the secret to trashing your system beyond
