For what little it's worth, I haven't experienced this crash again, but
after a bumpy period I stopped running concurrent X sessions. X
stability has been much nicer in general, though, since the time when I
reported this, during a period when several releases were described as
Merge from
no hangs anymore (quantal release)
Still got some glitches (Artifacts) with desktop effects enabled

Title:
[Intel HD4000] GPU lockup IPEHR:
I think this is a regression - had same issues with my older laptop (Lenovo
x220 and x201 Tablet) now got a x230
(00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller (rev 09))
Error is slightly different:
[drm:i915_hangcheck_hung] *ERROR* Hangcheck
Status changed to 'Confirmed' because the bug affects multiple users.

Title:
[Intel HD4000] GPU lockup IPEHR: 0x0100 IPEHR:
When you say you had two different user sessions each on a different vt,
were you running two instances of X.org, or do you mean you had a vt
console login and were toggling between that and your X session?
I can see from the log file that the GPU lockup directly occurred after
a vt switch
Hi Bryce -
Two X sessions. I knew that description didn't seem good; I'll update
it.
I cannot reproduce it at will, or at all, so far. I've had problems a
number of times when switching between two X sessions, but certainly in
a minority of those events. Most of them I've considered bug
