there are several others. The problem is that I cannot remove them, or
do just about anything else to them even as root. For example:
[root@bitmap peg]# chmod +rw pre-patch-2.2.5-1
chmod: pre-patch-2.2.5-1: Operation not permitted
here is the strace output of the above:
[root@bitmap peg]# strace chmod +rw pre-patch-2.2.5-1

Notice the EPERM error return on the chmod call.
The question I have is how do I remove them. I've run fsck on it and
it shows up clean. This is an ext2 fs. As a side note du does not
handle these files very well, e.g. du -s Tmp returns total 665299597
and it contains:

so the character device file is causing du to return a wrong value.
Any help on removing these files would be appreciated.
As for my IDE tape problems I posted last week, even by patching
ide-tape.c to version 1.15 I still see tar locking up. I also got
this message when I tried to copy a file to the floppy drive while
the tar was hung up:
DMA memory shortage. Temporarily falling back on virtual DMA.
