Better than nothing.

We've had a few clear_inode()-related crashes lately, but mainly
NFS-related. This one looks more like a reiser4 thing though.

Is it reproducible?

This is probably the same I get unmounting a reiser4 partition.
I got the oops through netconsole, attached to avoid line wrapping.

Oh, yep.
I just tried umounting /home.
Bugs too, but system keeps running, so I could easily catch the dmesg:
