Hi.
I updated my ports, including xf86-video-intel to 2.7.1and the other
X-related ports.
The chipset is an Mobile Intel GM45 Express.
The server is mostly stable. But moving large videos around different
screens is still crashing the servers, I think (but don't dare to
test).
Another issue is more enerving: Switching with Ctrl+Alt+F1 from the X
server to ttyv0 causes an assertion to fail.

Does anybody have a workaround other than downgrading to 2.5.1?
BTW: Disabling the assertion and executing the block in I830EmitFlush
only when batch_ptr != NULL does not help... ;-)
