Comment 16 for bug 539655

The fatal effect of locking up is verified to be gone in current Lucid and Maverick (daily live CD 2010/07/12). If I understand the comments before correctly, this is done by automatically not using DRM rendering, when there are more than one active output present. The visual result on this particular hardware is that the boot logo is rendered in the wrong size but not hard lockups occur.

So I would say the hard lockup is solved and I would close this bug, but there is a still is a much less critical issue of fixing the case of two outputs on boot (likely when not having the same resolution like being in mirror mode). But that should be a different bug.
