Yes.  And the other error code (-110) indicates a time-out.

Can you test whether the attached patch fixes this?  You can do this by

At least we can now rule out that it is not related to the issue you

We can't draw the conclusion that the crash is in hypervisor yet. If
your dom0 crash, hypervisor would normally decide to reboot the machine.

Yeah, it is segfaulting, because the database (in a domU VM) where it is 
storing the accounting is not yet available after the crash. When 
database is up, those segfaults go away.



Still not sure what to make of that though.


Me neither. ;-)

I already tried to get a core dump by setting ulimit -c unlimited, but 
that didn't work as well, which makes me believe that the crash happens 
in hypervisor not in dom0 kernel. When it's dom0 kernel I would expect 
dumping a core file should work.

What is also interesting is that you seem to be running some sort of
ip accounting software (pmacctd) which also segfault'ed.

Still not sure what to make of that though.

Bug#833247: linux-image-3.16.0-4-amd64: DRM/i915 "blanks" display and dumps trace

[Rafal Pietrak]

Package: src:linux
Version: 3.16.7-ckt25-2+deb8u3
Severity: normal

Dear Maintainer,


   * What led up to the situation?
I vagually correlate it to a prolonged "runtime" of my notebook. I don't
power it down ever, but only put it into suspend mode. Currently it has
14 days of uptime, but it happens to have 100 days or more.

   * What exactly did you do (or not do) that was effective (or
 ineffective)?
I honestly don't know.

   * What was the outcome of this action?
The screen goes "blank" in a strange way: first it blanks-black, then 
after 5-11 seconds it becomes "white becklited" from top left corner
in a "hash pattern" with 1mm grid size. When the display blanks black, I
can bring it up to normal display "mode" with a mouse (but not with a
keyboard).  When it becomes "grid-patterend", only suspend-by-closing
the lid helps.

   * What outcome did you expect instead?
obviosly - normal operation.
