Something I would like for you to try first before you do anything else 
is to do a search for free and non-free firmware and install what is 
missing from your system and then install the package "upgrade-system" 
and run 'upgrade-system' from the console, let it do what it wants to do 
even though what it will want to do may scare you, this software script 
has never let me down, never, and I run many systems from stable to sid. 
If more people ran upgrade-system I would see less problems in this group.

A failing power supply and/or off-spec memory module can cause 
unpredictable lock-up's.



I use an inexpensive ATX power supply tester for quick pass/fail testing:

http://www.newegg.com/Product/Product.aspx?Item=N82E16899129001


I use memtest86+ for checking RAM:

http://www.memtest.org/

Run memtest86+ for at least 12 hours; better 24.  I've seen machines 
with infrequent lock-up problems pass an hour or more of testing, only 
to fail once or twice in later hours.



If your new computer fails either of the above, return it.


If the memory and power supply test out okay, then understand that the 
whole point of the Debian "testing" release is to find bugs.  Here is 
your opportunity to do so.

If you're going to re-install, a fresh ISO would be a good idea.  I 
typically run amd64 on compatible hardware, but i386 with PAE (default) 
supports more than 4 GB of RAM too.  Installing and running Wheezy for a 
week or so should narrow the possibilities.

Couldn't find that model listed anywhere.  Even searched ebuyer's site.
Nothing. Just trying to get the specs on it.  Curious.  No matter as it
seems installing watchdog solved your problem.  Although, why watchdog
wasn't installed in the first place or why it needed to be installed at

When GNOME went to 3, I stopped using GNOME.  It caused more problems
than it was worth. Even installing another environment or just
using a window manager, it still got in the way.  Ultimately, when I
upgraded to Debian Wheezy (from Fedora 12) I did a netinstall, Basic
System.  Added what I wanted -- X, etc. -- service by service,
app by app.

You should be able to choose which environment or window manager you
want on the login page.  If you set Fluxbox as the Default, system
should boot to it the next time and every time until you change it.

You said you upgraded from Wheezy.  When or if, you reinstall Jessie,
just get the latest version and do a clean install.  I've never done a
distribution upgrade that didn't require fixing in some way or other.
Clean installs are the least problematical.

I agree with the previous reply from Patrick. Install 64 bit Jessie 
fresh. I don't have anything 32bit installed to my machine, and don't 
miss it. But, if you only have 1 gig of ram, then you might have to go 
32bit.


Consider the tired feet remedy; "Let it soak". Give your install some 
time to settle in, before adding new things.

Did you, by any chance,  install a 3.19-trunk Kernel? That one crashes on my

Everything is working okay, that crashing was the only problem, so
thanks, but I'm staying with it as it is. The setup was missing
"watchdog" which is now installed. But it is a good idea to get a
new 64-bit version, my install disk was burnt on 28 May 2013 so it
does need to be replaced.

What OS did it come with Windows 7 or 8?  Did the machine crash when
running Windows?  If yes, you could have a hardware problem.  If no,
then it's probably a Linux problem.

You seemed to have installed Jessie 32-bit based on your other posting
-- "installed watchedog" . . . i386.

What version of Jessie?  It's at RC1 as of 25 Jan.

Dual boot or did you wipe out Windows?

GNOME3 desktop?

Here's what I'd do.  Start over from zero.  You could have a corrupted
install.  Wipe out your current Jessie.  Download and install the most
current 64-bit version. Do a checksum on the download itself and the CD
or DVD after burning.  Depending on your Internet connection, a
netinstall CD will get you an up-to-date system when the
install is completed.

Sounds like a kernel crash.  Does the screen go black (or another

remain?

After looking more closely I don't have "watchdog" installed! There
is no conf file for it, there is no executable for it, there is no
man page for it, and apt-cache-policy shows

--8<---cut here---start->8---
acp watchdog
watchdog:
  Installed: (none)
  Candidate: 5.14-3
  Version table:
 5.14-3 0
500 http://mirror.bytemark.co.uk/debian/ jessie/main i386 Packages
--8<---cut here---end--->8---

which is why the machine freezes when its called, and also why it
segfaults! Logically then, if the machine freezes without it, I need
to install it, which I've just done. And so I'll just wait and see
what happens now.

Thanks all
Sharon.

So can I get round it by stopping or disabling the watchdog? I don't
know what its doing and haven't deliberately installed it. It just
seems to have appeared from somewhere!

No, the user "glances" was auto-created when I installed glances
yesterday.

You appear to be running a watchdog process, which is crashing. A
hardware watchdog will, generally speaking, work as follows: at boot, it
will do nothing, but when an application writes a specific command to
it, it will start a timer (30 seconds, 60 seconds, etc. Often
configurable). When the timer expires, the watchdog will cause the
computer to reset. However, when the application writes the command to
the watchdog again, the timer is reset back to the start. So, as long as
the watchdog process is alive, it is able to keep resetting the clock
and the machine works fine. But if the processes stops (because the
machine has hung, or the system is too busy), then the timer will
expire, the machine will reboot and you can get back to work.

In your case, though, it looks like the watchdog process is dying
because of a Segmentation Fault (see the full logs or a core file for
full details). At that point, even though the rest of the system is
running fine, no-one is resetting the watchdog clock.

You are seeing Machine Check Exceptions. These may or may not be a
problem. This is usually the CPU saying "I ran into an error". This
could be the cause of your Segmentation Fault, for example - the
watchdog executes an invalid command, the processor complains and the
watchdog receives a SegFault as a result. I suspect the difference
between this and a SIGILL (Illegal Instruction) is that, while the
instruction is technically valid, the data or the state of the processor
or something like that is resulting in an error. It IS possible that the
code is perfectly correct, but the processor is calculating the wrong
answer (because of a hardware error).

You've included this information. Did you not create the user "glances"
yourself?

Hard to say without more information. The next time it crashes, you
might want to note the time, and look at messages in /var/log/dmesg
and /var/log/kern.log for messages around that time period, and post
them here and/or post a link to a pastebin of the logs.

Then it might be easier to figure out what is going on.

Hope you can do that, and that it will help. Trouble with new computers
is never any fun :-(

Lenovo 050 desktop crashing

2015-02-24 Thread Sharon Kimble
I have just bought a new computer,a Lenovo 050 desktop. Its working
reasonably okay except for the occasional crashes. For instance, I've
had it a fortnight now and its longest uptime has been just over 3
days, even though its on all the time!

It has crashed when I've been using it, and its crashed overnight
whilst I've been asleep! There does not seem to be any pattern to
it, or any noticeable trigger.

When it crashes, the screen freezes, and both the usb keyboard and
mouse freeze, and can not be used.

In its most recent crash, it shows this in logwatch the following day

--8<---cut here---start->8---
 - Kernel Begin

What should I -

b) - do to stop/get round the crashing please?
