This error message has been added to Tramp 2.5 in order to get more
diagnostics when the problem happens. It is an indication that a remote
opeation has been started asynchronously, from a timer, a process filter
or sentinel, or other asynchronous invocation (like interrupt process).
I don't believe it has been fixed yet in Emacs master, I haven't done
anything in this area for weeks. I'll try to fix your use case, but it
might take time - these days I'm occupied otherwise. Holiday season.
See the respective entry in Tramp's FAQ (info "(tramp) Frequently Asked
Questions")
