I really think that the anon_vma and i_mmap_lock spinlock hangs are due to the lack of queued spinlocks. Not because I have seen your system hang, but because I've seen one of Larry's test systems here hang in scary/amusing ways :) With queued spinlocks the system should just slow down, not hang. -- All rights reversed. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
