3 links to bug reports elsewhere instead of putting the info in the bug report,
and none of them even have a backtrace. Sigh.
Anyway, this got fixed thanks to another bug report:
commit 024ece7523f1735d2fca0067c0a3bdcf53fde8f9
Author: Kurt Roeckx

i915: Compute maximum number of verts using the actual batchbuffer size.
We were looking at the size of batch.map for how big the batchbuffer
was, but on 865 we just use a single-page batchbuffer due to hardware
limits.
v2: Removed check for sizeof map < bo->size, since that's always false.

i830: Compute initial number of vertices from remaining batch space
In order to prevent an overflow of the batch buffer when emitting
triangles, we need to limit the initial primitive to fit within the
current batch. To do we need to measure the remaining space and thence
compute the maximum number of vertices that fit into that space.
