Yes, based on where the CPU lockups were occurring (zone_nr_free_pages, zone_watermark_ok), this fix does seem to address the problem I described. I assume the other lockup points (_raw_spin_unlock_irqrestore, find_next_bit, sleeping_prematurely, test_tsk_thread_flag) are also caused by the NR_FREE_PAGES problem?
Thank you for the link, I'll put it into the Fedora bug report and hopefully a fix will be pushed out sometime soon.
Luke
