David, Peter, can we get the official kernel spun with this. It's going to be upstream shortly, has been ACKed by folks. Just swap the revert patch for the atomic fixup patch I posted if possible. Here's the upstream ACK: http://lists.infradead.org/pipermail/linux-arm-kernel/2012-October/127317.html This should be in a kernel near you soonish, so I really see no problem pulling into our 3.6. After all, it's more official than the revert patch we already have as the real solution to this problem. Separately, there are some unrelated highbank network performance fixes, but as you can see from this mail from Jon, it's not highbank specific the alignment fault handler triggering these BUGs.

[fedora-arm] BUG: scheduling while atomic: swapper/0/0/0x40000100
Hey team, I've been seeing lots and lots of these OOPS on Pandaboard ES with recent'ish f18 image. By lots and lots I mean hundreds per second, causes log spam, and eventually eats all the inodes in /var/spool/abrt making reports.
