Last days recent pretest caused two times a system freeze, restart required.
Unfortunately  couldn't reproduce with Emacs -Q
As this didn't happen last year --but sometimes the years before-- maybe 
it's a valuable info though.
A crash happened after M-x edit-abbrevs RET, editing

A full system freeze? That's pretty impressive. Was it maybe a runaway
allocation causing the system to swap?

The edit-abbrevs has a design-issue, dealing with all when changing one. 
Maybe that turned exponential?

But even if so, that would only lock up a single core -- unless it was busily
trying to create an abbrevs file as big as all available disk space, while at
the same time filling memory...

The other form causing a restart was navigation-related inside an 
incomplete form of

(when (setq VAR (FUNKTION ARG))

Probably not really helpful at the moment, just wanted to get it known,

Can you provide more details about these system freezes?  Some
questions:

 . What exactly freezes?  Can you start a new application, or move the
   mouse pointer, or ping the system from the net?

 . What do you see in /var/log/messages around the time of these
   freezes?

 . When it freezes, do you see the disk I/O indicator lit, indicating
   some disk I/O, or is the indicator off?

 . Any other relevant details.

Thanks.

Hi Eli,

system was completely frozen, no message, no mouse, no reaction at all.

At the time thunderbird was open too. Maybe it was caused by an attack 
from there.

Thanks,
Andreas

Then what you find in /var/log/messages around that time may be the
only clue to what happened.  Please see if you find anything
interesting there.

Hmm, looks dbus related -  the part of the messages have been sent 
off-list.
Could run Emacs in some debug mode.
Any suggestions? valgrind exists here.

No, I don't think dbus is related, its message just says that the
system is being shut down.

If the system freezes, how can a debugger help?  You will be unable to
get any response from the debugger.  Or does something remain unfrozen
after all?

Hi Andreas, do you have a second system that you can use to (try to) ssh
into the hung system, or at least ping it?

Earlier in the year I had a reproducible system hang that was apparently
related to a video driver lockup.  The problem went away if I switched
from MATE to Xfce, or if I disabled thumbnails in the MATE alt-tab
window switcher.  A couple days later there was a kernel update that
included a fix for the video driver, and after that I could no longer
reproduce the hang.

What sort of desktop environment are you using?

regards,
mike

Thought at some logging, dumping.

Not in this both recent cases.

Yes, have a second one, Xubuntu. Could try that.

Did you try https://en.wikipedia.org/wiki/Magic_SysRq_key ? (sometimes
they are disabled though)

/sbin/sysctl -a gives me a value  for kernel.sysrq
However a key like

Alt+SysRQ+m

which should print memory information to the console.

according to

http://linuxhowtos.org/Tips%20and%20Tricks/sysrq.htm

seems to have no effect.

SysRQ understood as the print-key.

Thanks,

Andreas

WFM, but perhaps your sysrq key is elsewhere ?

Also check if it appears in your dmesg output : sometimes the logging
level of your console simply won't show the sysrq messages.

If that doesn't work I'm afraid I don't have any further suggestion.

Nicolas.

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

This morning the keyboard messed up X-wide - backspace in X didn't work 
any more.

Wrote the following into some buffer in sh-mode:

${WERKSTATT=1}

See attached png what was displayed, when trying to M-x report-emacs-bug 
from emacs -Q

Send the results of M-x report-emacs-bug after restart, which might 
provide some info still.

Looks like your Super key is stuck pressed?  Otherwise, why does the
image show a message about M-s-x being unbound?

Other than that, I see nothing of interest in the image you posted.
Did I miss something?
