Comment 1 Chuck Ebbert 2011-09-14 09:32:42 UTC

According to this report there were BUGS generated before these. Can you find the first reported one in the logs? (It should say "not tainted" where these say "Tainted: G    B".)

Comment 2 Mark Knoop 2011-09-27 18:57:48 UTC

Sorry for my slow response...

You're right, there were previous soft lockup bugs mainly triggered by rsync, perhaps related to bug 729779. There have been no other bad page map bugs however. 

According to /var/log/messages the previous "not tainted" bug was reported as bug 733608.

Comment 3 Dave Jones 2012-02-21 23:56:17 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.

Comment 4 Mark Knoop 2012-02-22 09:36:56 UTC

Yes, I've not seen it since 3.2.
