Sorry, I thought I had included that. The result was a little funny.
It said that the address pointed to vfs_vmio_release in atomic.h line
I tried to ``panic'' the system to get the core dump (I have dumps
configured), but it locked up, and not even a ``continue'' would work.
Since then, I'm on a slightly newer kernel, and so far, no crash. If it
dies again, I'll send more details, and hopefully get a core dump.
Thanks for the follow up.
