[Message part 1 (text/plain, inline)]

This happens for me on two different computers, Windows 10 and Windows 
8.1. I don’t know what more info to provide than “it happens”, I can 
provide stacktraces on some scenarios but not on all since C-g doesn’t 
work all the time.

Could you, please, provide more details? Which Emacs version are you
using?

Is it reproducible? In case of yes, do you have a recipe that we
could reproduce it? Do you apply auto-revert-mode on buffers related to
remote files?

Does it also happen when you start "emacs -Q", that means with out
evaluating your .emacs or init.el file?

Thanks, and best regards, Michael.

The freeze happens for example when opening files using Tramp+plink in 
Dired. Tested Emacs 24.5 and 25.0.94.2 (64-bit precompiled for Windows).

Regarding auto-revert-mode: Yes I have global-auto-revert-mode set to t.

"runemacs.exe -Q" makes this variable (auto-revert-remote-files) not 
show up with customize-variable.

I reproduce this bug by going into Dired+Tramp+plink and select file 
after file doing C-o for each one, Emacs eventually hangs.

Kind regards,
Andreas

Please call "runemacs.exe -Q -l autorevert" then, and change
`auto-revert-remote-files' to t in the Customization. Could you still
repoduce the problem?

And what is the value of `auto-revert-use-notify'?

runemacs.exe -Q -l autorevert

version 25.0.94.2 (x86_64-w64-mingw32)

Set global-auto-revert-mode and auto-revert-remote-files both to t and do:

C-x d /plink:SOMEHOST:/home/blah

Open lots of files with C-o until Emacs goes into escapable freeze. From 
what I tested the freeze is escapable with C-g using -Q but what I 
experienced with no -Q was that it locked up Emacs most of the time not 
escapable.

auto-revert-use-notify is nil

How many files have you opened (you say "lots of files")? Could it be
that you haved stressed poor little Emacs too much, out of what is a
fair use? Every remote file in auto-revert-mode needs to be polled every
5 seconds for changes.

How does it work, if you increase auto-revert-interval to a larger
number, say 20?

Could you bisect your init file in order to find the culprit which makes
Emacs unresponsible for C-g?

Best regards, Michael.

Hello!

I just tried the same thing with Tramp+SCP in Arch, nothing to report.
I guess this is a problem with Plink and Tramp toghether (Windows).
Maybe the bug is not at all in Emacs but instead in Plink? At least
this is reported as a problem, I will keep in touch if I experience
anything using SCP.

Regards,
Andreas

Hello again.

I have to re-open this one because it was my bad, Emacs actually locks
up still when using this option... Is it not locking up for you?
I somehow made Emacs not have this behaviour even though they are both
set to t, that is global-auto-revert-mode and auto-revert-remote-files,
what could be wrong now?

Regards,
Andreas

Wich PuTTY version are you using? 0.63 as a problem which also affects
Tramp, see

I cannot say too much about; I don't use MS Windows. Sorry.
