I cannot reproduce it locally. Could you, please, start a fresh Emacs
via "emacs -Q", rerun the test, and create then a new message via "M-x
report-emacs-bug". This will show us the last keys you've entered.
You do not need to send the created message as-it-is; you might send it
to <5414@debbugs.gnu.org> in order to follow this bug's history.
Best regards, Michael.

See how it says "loading tramp"?

Negative. I have applied exactly the commands; Tramp is not loaded.

Which emacs-snapshot is this? Debian?
Best regards, Michael.

Here's a proper recipe for reproducing this (the previous recipe does
not do it, maybe it was untested):
emacs -Q
C-x C-f
C-a C-k
/sys/devices/pc [TAB]
=> Tramp will be loaded

Thanks, I can reproduce it as well.
Tramp is loaded due to `rfn-eshadow-update-overlay'. In the loop
commented with "Binary search ...", it recomputes `mid', and calls
`rfn-eshadow-sifn-equal'. This function applies
`substitute-in-file-name' for a part of the the whole file name, which
looks like a remote file name, accidently. Bingo!
See the backtrace:
tramp-file-name-handler(substitute-in-file-name "/pci0000:00/")
substitute-in-file-name("/pci0000:00/")
byte-code("ÁÂ\bd\"!‡" [pos substitute-in-file-name buffer-substring-no-properties] 4)

rfn-eshadow-update-overlay()
run-hooks(post-command-hook)
I wouldn't regard it as a bug. One could argue, that rfn-shadow should
deactivate file name handlers for its work, but this might result in
collateral damages.
Best regards, Michael.

Thanks for tracking this down. I agree, there doesn't seem to be any
satisfactory way to get around this. I'll close the bug.

Chong Yidong's recipe works for me, here with
$ ls /sys/devices/pc*
