This causes an eventual (after barely a minute of use) lockup that I can
not recover from on my Lifebook S761. It does not switch to a text
console for me, but by stopping my graphical login manager (slim) early
I got this:
DRHD: handling fault status reg 3
DMAR:[DMA Write] Request device [00:02.0] fault addr 12806b000

(The full dmesg is attached so you can see it in context)
In the interest of full disclosure, this is a dual-screen setup:
Screen 0: minimum 320 x 200, current 1680 x 1818, maximum 8192 x 8192
LVDS1 connected 1366x768+0+1050 (normal left inverted right x axis y
axis) 293mm x 165mm
HDMI2 connected 1680x1050+0+0 (normal left inverted right x axis y axis)
459mm x 296mm

To confirm, that is the i915 graphics:
