It is still not established you're running into #991967.  Unless the one
you're pointing towards was backported to the Xen 4.11 packages (which I
doubt) it cannot explain #991967, since at the time 4.11 was in use.

Could be this is a second bug with symptoms similar to #991967.  Now
that a fix for the second bug has been identified, you might try a
4.19.181-1 kernel and see whether that fixes things.
