This looks like either just a timeout or a bug in the windows-amd64-race runtime (attn @golang/runtime).

There is one goroutine in the running state, but the goroutine dump doesn't include it.
It's not clear to me whether it that goroutine is making progress or actually wedged.

goroutine 17248 [running]:
	goroutine running on other thread; stack unavailable
created by golang.org/x/tools/go/packages.(*loader).loadRecursive.func1
	C:/workdir/gopath/src/golang.org/x/tools/go/packages/packages.go:845 +0xee

In addition, there is one goroutine in the runnable state, and the rest of the (numerous!) goroutines seem to be waiting for it to complete:

goroutine 18238 [runnable]:
