820-3787-A No boot with trackpad connected

[dr. moast]

Hi,

I got a 820-3787-A here which will turn black during booting with the trackpad connected (similar to the U9300 issue) but will boot fine without trackpad. If I connect the trackpad after boot, it works without issues. Also shows up as USB device.

In verbose mode the last line before turning black is "Airport Link Up on awdl0". Removed Airport but still same behaviour. Also, AP and BT work without issues.

Any idea?

Thanks!

Nah, it is the usual 3662/3787 issue. Without trackpad the CPU is clocked down so it will not crash. Still no solution as I have no time to spend on this.
