If I understand this bug report and its dupes, the gpu appears to hang
but the kernel is able to reset it, so it triggers the gpu hang capture
tool, but doesn't actually leave the system in a hung state.
When 10.10 was released, the automatic hang capture tool was turned off,
which explains why this stopped happening after that.
For natty, we've updated to a newer kernel, which I presume includes a
fix for whatever was triggering the capture tool to be called.
Has anyone seen this bug on arrandale with natty?
