kernel update causes ps to segfault

[Lindsey Simon]

Since upgrading the kernel on our webserver, when root runs ps, it
segfaults.

Unable to handle kernel NULL pointer dereference at virtual address

I get nothing with gdb cause there's no debugging symbols in ps.

That isn't a ps bug, it's a kernel bug.
Please pass it through ksymoops and send a full bug report to
the kernel lists.
