Comment # 2 on bug 1188487 from Petr Mladek

Tom, do you still see the problem please?

Could you at least attach full kernel log provided by dmesg?

The pasted piece looks like a mix of lines from dump_stack() triggered from XFS
code on CPU 3 and workqueue lockup report on CPU 0. These might and might not
be related.

It might also be interesting to do fscheck of the XFS file system. I wonder if
it has got somehow corrupted.
