That is EINTR, wasn't that related to the change where we started using
ucontext to switch LWP threads. I thought all the context switching
issues were resolved.

It is trying to send the reply to a CODA_OPEN upcall (opcode 4), but the
kernel only expected to get 20 bytes.

    struct coda_open_out {
	struct coda_out_hdr {
	    u_int32_t opcode;
	    u_int32_t unique;
	    u_int32_t result;
	}	      oh;
	dev_t	      dev;
	ino_t	      inode;
    };

Did device nodes or inode numbers happen to switch to 64-bits in userspace?
