Long running stable systems exhibit the following with all mods removed, as
distributed. (I use my own scheduler and file system - the kernels below use
the stock ext4 file system):

V3.17 and earlier kernels run like champs. This regression is independent of
Mesa (versions 9.2.5 - 10.3.2), xf86-video-intel (any up to and including
2.99.916), libdrm up to and including v2.4.58, as well as other boards
utilizing the i915 driver. I use the Gallium driver as I need OpenGL V2 support
- I can't begin to express my gratefulness for the Gallium driver. This error
also shows up on an Asus board as well as two (2) other Elite motherboards -
what a misnomer that name is.

On 3.18-rc1, the page flip problem only happened if you ran an OpenGL consumer.
Rc2-Rc5 would always log the problem at boot time with no OpenGL consumers.
Then in rc4 AND rc5 performance worsened the over the course of about an hour
and the machine hard locks up. The only recovery possible is to cycle the
power. The hang leaves no trace whatsoever. Also introduced in rc5 only, after
the Gnome desktop startup, the screen flickers and distorts rendering. A page
table problem? (I also tried using i915.use_mmio_flip=1 as a parameter.)

Enclosed is the kernel .config file common to all kernels using Intel embedded
graphics.

I donate my time in the Philippines teaching all ages computer science and as
such I can only afford used hardware, or computers that are donated, in my
classes. hence the importance of these old drivers. My newest machine (except
my personal) is a core 2 processor. (LGA775 socketed motherboards.)

Besy regards,
