Jeremy: Is this already known bug/crash?
I don't recognize it.  What CPU is it?  It would be useful to work out
exactly what line is crashing.
The server is equipted with two AMD Opteron 2218.
What to do to find out the line in code that crashes?

If you built the kernel, then:

$ gdb vmlinux
(gdb) x/i 0xffffffff81386142  (or whatever the RIP line says)
(gdb) list *0xffffffff81386142

The first just shows the faulting instruction, and the second should list the actual corresponding source line.

You'll get best results if you enable CONFIG_DEBUG_INFO.
