I get "Fatal double fault" error when writing to a filesystem

I got an offlist reply in which he suggested that the problem might be
in nve driver.
That was me. I indeed got the same fault when running NFS over nve.
Switching to nfe solved the problem for me. The on-screen backtrace
reveals the true location of the problem. See:

I do have a dump, but for some reason kgdb is not able to show the
same information.
If you're using a module you have to do extra (but documented) steps.
Or maybe kgdb has forgotten how to decode a double fault.
Anyway, this information is indeed definitive, and it's what others
seeing this problem need to provide if they still have doubts.
