Yes, it's definitely an osboot problem... Please report the issue to osboot folks, and point them to this ticket.
After grabbing the T440p IFD.bin that osboot uses and using `util/ifdtool`'s `-d` option on it (after manually padding to 12 MiB; you can just use the osboot image you built), it's clear why coreboot thinks the flash chip is much larger...
Component 2 Density: 32MB Component 1 Density: 8MBComponent 2 Density should be "4MB" (technically, 4 MiB) instead. No clue where the IFD.bin that osboot uses comes from, but it's broken. See attached log for the complete `ifdtool -d` output.
I appreciate you looking into this. I have submitted an issue here: https://notabug.org/osboot/osbmk/issues/161
For what it's worth, there was some discussion here on using an extracted IFD from a Lenovo-provided archive: https://notabug.org/osboot/osbmk/issues/129
---------------------------------------- Bug #432: t440p reboots on suspend https://ticket.coreboot.org/issues/432#change-1219
* Author: Josh R * Status: Response Needed * Priority: Normal * Target version: none * Start date: 2022-10-21 * Affected versions: 4.15 * Related links: https://ticket.coreboot.org/issues/412
* Affected hardware: Lenovo ThinkPad T440p * Affected OS: Ubuntu 22.04 (Pop OS) ---------------------------------------- Per request, adding new ticket for an issue with my t440p where attempting to resume on suspend results in a reboot (or at least, not resuming from DRAM).
My t440p already has coreboot installed (via osbmk). Following instructions from issue #412, I have attempted the following:
`sudo flashrom -p internal --ifd -i bios -w the_full_12MiB_osbmk.rom --noverify-all`
...but that did not seem to do the trick (still "restarts" without resuming from RAM).
Note that I am using the "full" 12MB osbmk rom (not split by 4MiB and 8MiB, as that seemed intended for the hardware flashing instructions).
coreboot version looks like 4.15.204, and flashrom version 1.2-640.
If it helps, attached cbmem -1 output with a "normal boot" followed by a later resume from suspend (that resulted in a restart).
Thanks in advance. I guess you don't realize how much you use suspend until it doesn't work anymore :)
