Issue #449 has been updated by Angel Pons.
https://review.coreboot.org/72806 fixes the UBSAN errors, please review. Note that UBSAN-enabled coreboot still dies later on:
``` Loading module at 0x00030000 with entry 0x00030000. filesize: 0x178 memsize: 0x178 Processing 16 relocs. Offset value of 0x00030000 unaligned access src/lib/rmodule.c:152:27 ubsan: unrecoverable error. ```
So, any users that desire to have a bootable system should keep UBSAN disabled when building coreboot.
---------------------------------------- Bug #449: ThinkPad T440p fail to start, continous beeping & LED blinking https://ticket.coreboot.org/issues/449#change-1394
* 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: 4.19 * Related links: The USBAN error is:
``` [ERROR] shift out of bounds src/northbridge/intel/haswell/pcie.c:85:22 [EMERG] ubsan: unrecoverable error. ``` * 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)
