Description

Hi, Team
Being corebooted before and works fine on 4.17.

After flashing 4.18 my t440p wont startup (black screen, constant beeping & LED blinking). I've tried and retried different nconfigs but result is the same. I know that it is lack of information, but I need to recover the laptop first to grab some logs from it.

Log from FT232H's debug is attached, the rest of info (defconfig, flashrom command etc. will upload soon)
