This is a MASTER bug report, i.e. not a real bug report, but a tool to help manage other bug reports.

Most bug reports on i855 are probably due to the CPU/GPU incoherency problem that is now consolidated upstream at http://bugs.freedesktop.org/show_bug.cgi?id=26345 (which was originally reported for i845, but applies to i855 as well). For now, we mark all automatically reported GPU lockups on i855 as duplicates of this unless there is a reason not to. There are some tests you may do to help upstream with this issue, and I will come back with instructions here. For those of you who know how to patch and compile a kernel you may look at comment #61 in the upstream bug report.

There is a similar master bug report for i845 at bug 541492.
