Looks like coreboot dies because UBSAN encounters a bug. Please disable UBSAN and try again. Note that things like ASAN and UBSAN are meant to be used for debugging purposes; for "production" use-cases, it's better to keep these options disabled.
You are right - after disabling UBSAN everything is working fine, thanks for directing me!
---------------------------------------- Bug #449: ThinkPad T440p fail to start, continous beeping & LED blinking https://ticket.coreboot.org/issues/449#change-1368
* Author: Crazy Fox * Status: In Progress * Priority: Normal * Assignee: Angel Pons * Category: board support * Target version: 4.18 * Start date: 2023-01-14 * Affected versions: 4.18 * Affected hardware: haswell ---------------------------------------- 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)
