Comment 1 Dave Jones 2012-02-21 23:56:26 UTC 
[updating multiple bugs at once]

There are a bunch of these 'bad page map' bugs now, and the only thing in common is that they're all on kernels before 3.2 (or 2.6.42 for f15), so I'm optimistic this is fixed in the newest update.

Can you try and reproduce it with the latest update ?

If I don't see any reports from 3.2 in the next week, I'll close these out.
