This is not a xen problem. I believe it's a gpfs problem on the
shutdown/umount path. We're using gpfs with a kernel version that it
doesn't support yet and I have fixed problems related to clear_inode
before (Linux has changed some interfaces in the vfs layer on 2.6.17).

I got the following error this morning from the console on one of our
JS21s. I had a program that was supposed to ssh into the blade and reboot
it after shutting down GPFS. I don't think it did any of the gpfs shutdown
before crashing. Here is the error message. I saw it because I happened to
be on the SOL console ( I wouldn't normally be). This is the first time
I'm noticing this. I will post again if I see more errors of this kind.
