I just had a lockup without Virtualbox running, but it anyway happened in firefox4. It looks like this lockup happens when the load on the machine is high, and firefox is running with many windows/tabs, or at least this is the situation I had at the last lockup. This al looks very nasty. I'm trying to give as much data as I can to isolate this, if anyone is interested/has time. I'm also not quite sure if the LIBGL_ALWAYS_INDIRECT trick really works around the issue the issue. I'm now testing with it set in my .xsession, so all X clients get it. Also, cairo was already compiled without GL. If the problem still persists I'll have to disable acceleration, this should stop the lockups. :D -- Guido Falsi
