Issue #449 has been updated by Angel Pons.
Assignee set to Angel Pons Status changed from New to In Progress Category changed from coreboot common code to board support
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.
---------------------------------------- Bug #449: ThinkPad T440p fail to start, continous beeping & LED blinking https://ticket.coreboot.org/issues/449#change-1344
* 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)
