I was going to merge it, but there is another bug report where these changes
broke a different system, see the followups here:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=190186

Hmm, looking at the bug report about the hang itself:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193500

it seems that there is a workaround at least, but not yet a fix.  However,
since there is a viable workaround the gain from merging this probably
outweighs the downside.
