Yah, definitely this is uvm_loan() related, this is not a softdep
Can you please file a pr?
While this is probably not something I'd
be able to fix myself, Chuck Cranor or Chuck Silvers might be able to :)
It would also be nice if you'd be able
to provide -g compiled kernel with appropriate crashdump somewhere, Greg.
I guess the problem is not easily repetable, right?
