Picture taken of crash info on screen

Description of problem:
This has happened twice now, though I don't know how exactly. I have F15 (i386) installed on my Macbook Pro laptop. This is not my main computer, so it usually sits idle and I occasionally ssh into it for something that I have only running on that machine.

At some point I notice there is a black screen with some debug/crash report on it. This is screen wide, the KDE session I was running is not visible anymore.
I'll attach a picture of the data it displays.

How reproducible:
I haven't figured out (yet) what triggers this.

Additional info:
The last time it happened, I noticed my keyboard and mouse are still functioning. So I tried to switch to a virtual console. This worked (it took a little longer than usual). Then I switched back to the first console, and I got my KDE session again, exactly as it was before the crash.

I'm sorry I can't give you any more details. I don't even know what component caused this crash.

kernel BUG at fs/dcache.c:947!

                                printk(KERN_ERR
                                       "BUG: Dentry %p{i=%lx,n=%s}"
                                       " still in use (%d)"
                                       " [unmount of %s %s]\n",

This is probably bug 708039 - are you using NFS automounts?

Yes I am. Looks like the same but to me too.
