when using 'mkdir' to create a directory on an ext3 filesystem, a
regular file is created instead of the directory.
[2.] Full description of the problem/report:
I discovered this whilst writing a perl script, however, the problem
seems to be the same within a normal shell also. I was trying to create
a directory (in this case '.variable' off of my home dir) with the
command 'mkdir .variable'. When I then tried to 'cd .variable' I
received the error '-bash: cd: .variable: Not a directory'. The file or
directory '.variable' did not exist prior to this. To make sure, I then
executed the command 'rm -rf .variable' before trying the command
sequence again, with the same results.
I attempted this approximately 20 times as a test to see if it was a
permanent error or occasional, I also tried different directory names
('.variable', 'variable', 'test' & '.test'). In each case I managed to
experience the problem, I also noted that approximately 1 time out of 10
the mkdir worked as expected.
The root superuser does not appear to be affected by this problem.

[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
The PC is an IBM Thinkpad T21.
A friend also experienced the same problem, he is also using the ext3
filesystem which is the only commonality we can think of.
Currently I have the following filesystems mounted (if its relevant?):
root@voyager scripts # mount
/dev/hda4 on / type ext3 (rw,noatime)
proc on /proc type proc (rw)
none on /dev type devfs (rw)
tmpfs on /mnt/.init.d type tmpfs (rw,mode=0644,size=2048k)
/dev/hda1 on /mnt/win type ntfs (ro,uid=1000,gid=100)
tmpfs on /dev/shm type tmpfs (rw)
//defiant/drive_c on /home/russ/defiant type smbfs (0)
[X.] Other notes, patches, fixes, workarounds:
The aforementioned friend managed to circumvent the problem by cd'ing to
another directory then back again. I tried this, which allowed me to
mkdir one directory fine, but then the problem returned.
I also noted that root does not seem to be affected by this problem, I
cannot reproduce it at all as root.
