[1.] kernel oops in reiserfs under 2.4.2-ac28 and 2.4.3-ac3 when rming files
[2.] when removing a directory on my harddrive with rm -rf, i get this oops. 
it occurs every time i try, and only on this one folder (so far). its 
actually in a subdirectory of the folder, im guessing at one file, but i feel 
it wouldnt help much to find the exact file (and that would require about 100 
reboots). i also get a segfault, though not a kernel oops when running 
reiserfsck on the filesystem.

[6.] the command that causes it is:  `rm -rf /root/wine-directx`  its a wine 
source tree. tho any kind of access into the directory seems to screw me. for 
example a cvs update also does the same.
