> 5GHz WiFi has more bandwidth than 2.4GHz, so typically will involve larger IO buffers in the driver, which could easily be enough to expose a memory scribbler
He's saying 5 GHz will expose the scribbler, and the opposite is happening, only 2.4 GHz fails.
Although, if my theory that the IO buffers are different sizes is true, then that could perturb memory layout enough to expose/hide the bug in either direction.
I do agree that the different IO buffers might hide the bug in one instance, but I think this is just plain old RF noise.
I need more sleep.
