maybe it also could be due to some sort of wrong access to the
filesystem. What is clear is that the soft lockup itself is a kernel
bug, the problems here are what is exactly causing this bug (file
system, controller driver, hardware, kernel itself, ...) and why
glusterfs is triggering this bug and direct operations to the
ext3 file system or through nfs are not.
