Ping from Bug KDE 292706 Can we have the full backtrace here for this bug, please? Plus versions of libdrm xf86-video-intel and mese. And maybe slightly more details as to how this happens. 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 <kurt@roeckx.be> Date: Fri Mar 2 15:34:45 2012 -0800 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.

To do we need to measure the remaining space and thence compute the maximum number of vertices that fit into that space.
