Issue #474 has been updated by Bill XIE.


Other payloads (including grub payload built via ordinary way) will not trigger this \
bug.

https://ticket.coreboot.org/issues/474#change-1456

* Author: Bill XIE
* Status: New
* Priority: Normal
* Category: board support
* Target version: master
* Start date: 2023-03-28
* Affected versions: master
* Affected hardware: X200s
----------------------------------------
My X200s with panel LTD121EQ3B and 2x4GB identical RAM running a \
coreboot-4.19-937-g0b192d3238 built for X200, configured with the attached x200s.cfg, \
having the following contents, crashed with beeping after graphic init (screen \
lights), and before booting from the grub-based payload. 

```

```

This problem will disappear if I remove one DIMM, remove vbt files from CBFS, or \
enable EHCI debug with FT232H, which makes me unable to catch it.
