Reiserfs crash while deleting specific file in 2.6.2

Reiserfs crash while deleting specific file in 2.6.2

[Eric Buddington]

Kernel 2.6.2, not tainted.

My reiser root fs filled up while compiling, so I started deleting
extra files to make space. One directory in particular gives me a BUG
when I try to rm -rf it (I don't know if it's the same file each time;
the dir in question has no subdirs).

Running 'dmesg' afterwards to check messages hangs. So do other
commands I tried. I can still type at existing shells until I hit
enter, so I had to reboot.

When I repeated this at the console, I saw the following (which I had
to scribble on paper, so I just grabbed what I guessed was most
useful):

-----------
Kernel BUG at fs/reiserfs/prints.c:339
invalid operand: 0000 [#1]
call trace:
	reiserfs_do_truncate+0x34a/0x5f0
	reiserfs_delete_object
	reiserfs_delete_inode
	reiserfs_delete_inode
	generic_delete_inode
-------------

This is repeatable (2 for 2, anyway), and I will get more info if requested.

What if you run reiserfsck on it (you'd need to remount it readonly of course),
are there any errors reported?

There should be one or two lines prior to this that reiserfs itself gives.
If they do not fit on the screen, you might try to load smaller font
before reproducing.
