Sounds like it. Can you summarize all the data that we gather over this thread into one summary, e.g. - what kernel does it happens? Seems like 3.0 and 3.1 hit it easily, 2.6.38 some times, 2.6.32 is fine. Did you test anything between 2.6.32 and 2.6.38? - what hardware hits it often/sometimes/never? - what is the fs geometry? - what is the hardware? - is this a 32 or 64-bit kernel, or do you run both? I'm pretty sure most got posted somewhere, but let's get a summary as things was a bit confusing sometimes. Note that 2.6.38 moved the whole log grant code to a lockless algorithm, so this might be a likely culprit if you're managing to hit race windows no one else does, i.e. this really is a timing issue. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
