Applying the patch "ARM: vfp: Always save VFP state in vfp_pm_suspend"
solves the issue.

I tested with the above test case for several hours, and another OLPC
developer verified. No more bad calculations, no more crashes.

Any chance this effort could be revived? Looks like the patch was almost acked:

That was an old patch. We think the latest one is here:

This no longer applies due to last_VFP_context being renamed. I'll
send a v5 patch now to fix that.

Thanks
Daniel
