Bug#704696: linux-image-3.2.0-4-686-pae: System Becomes Unstable and Freezes or Reboots

Version: 3.2.39-2
Severity: important

Architecture: amd64 (x86_64)

Over this past weekend I upgraded my Wheezy system. Among those packages
upgraded was the kernel -- from version 3.2.35-2 to 3.2.39-2.
Almost immediately it became unstable. First, after just a few minutes in
graphical mode, the screen would become completely corrupted and the system
would freeze, requiring a power cycle hard reboot. Later, it sometimes would
just spontaneously reboot. Sometimes this would happen after just a few
minutes, more often than not, immediately after logging in.
I have tried different video drivers and different GUI's. The only thing that
helped was to swap out monitors, from a new one with a resolution of 1920x108
to an older one with a resolution of 1280x1024.
This happened on two different systems, one a year or so old and the other
brand new. I finally was able to fix the problem by downgrading to the next
older kernel, version 3.2.35-2. The video chipset is Intel Sandybrook, but
the problem occurred whether using the intel driver or the fbdev driver.
