Hi, have a weird problem with a MacBookPro A1502 820-3536.

It run extremely low when booting and it takes a minute to chime.

I've try to run asd162 but present kernel panic with a message of "failure missing me".

Bios flash chip have been flashed 3 times with different data but it behaves as with the original bios. (with clean me, of course)

I suspect that problem could be a damaged pch.

Can someone help with that problem?

Tested also with asd162 EFI, and didn't pass "Management engine presence test".

Another weird thing is that once boot process finish and enter into osx (mavericks) it runs pretty well and without lags.

Do you think it is problem from smc, or pch?

Thanks.
