You could have another bug at work (we've seen this before), or an
underlying condition that exacerbates the problem.

What this fix does is increase the size of the memory pool the gpu uses.
It's sort of like instead of requiring it to hit the bullseye on a
target we're just asking that it hit anywhere on the target or the hay
bales behind it.  So whatever causes your GPU to be such a bad shot
still exists, but it's not getting kicked out of the competition so
much.

In general, the two things needed for GPU bug reports are the 'dmesg'
and /sys/kernel/debug/dri/0/i915_error_state.  Look at the IPEHR value
especially, as that seems to be a roughly good indicator of dupes.  If
it's still the same values as this bug (0x02xxxxxx or 0x7xxxxxxx) then
your system may just be sensitive.  If it's a very different value, then
might be worth handling it as a second, unrelated bug and handling it
separately.
