This is a top crasher in Firefox 49.0b1. Looks like it started spiking recently, and only for 49.0b1.

It's often happening with Windows 8.1 (~70% of crashes with this signature vs less than 10% overall).
It's often happening with adapter_device_id=0x1616 (~90% of crashes with this signature vs less than 5% overall).
It's often happening with a particular CPU [GenuineIntel family 6 model 61 stepping 4 | 4] (~90% of crashes with this signature vs less than 5% overall).

Here are the reports with this signature for 49.0b1:

It's a pretty old signature (first seen on 2014-08-08), but the volume is big only in 49.0b1 for now (over the last week, there are 392 crashes with 49.0b1, 5 crashes with 48.0), which makes me think it's a different crash.

The number of crashes decreased to normal on 49.0b1 after Aug. 11, and the numbers of crashes on other versions are rare. I am tempted to move this to P3; feel free to specify the priority if you see a better fit, Olli.

looks like we crash in rather random places in EventListenerManager.
And the stack is usually very random. Missing parts or looking something which can't actually happen :/

I wonder if it's a CPU bug like the AMD one, since it's so strongly correlated with GenuineIntel family 6 model 61 stepping 4 | 4.
