Error 0x14 means instruction fetch in user mode. As both IP and fault
address are zero, my guess would be an attempt to call a (rem_port?)
method which has not been set. A core dump (or at least a stack trace)
would be definitely helpful.

This is a kernel warning, looks like an inconsistency in dentry cache.
I'm not familiar with filsystems code but this seems to point to a bug
in kernel code.

This is surprising. Looking at 3.2 kernel code, setting IPV6_V6ONLY can
only fail for two reasons:
- optlen < sizeof(int)
- local port already set (i.e. setsockopt() called after bind())
There are also universal reasons, e.g. invalid socket number, but those
would definitely cause more errors, not only one with setsockopt().
