Hello,
We are using intel atom C3558 denverton_NS platform. This platform is booting with coreboot4.16. Payload of coreboot is Seabios. Openbsd running in our board. Sometimes occur unexpected exception. You can find all coreboot and exception log above and you can find coreboot .config file. What is cause that exception. How can I solve it.

Stabbing in the dark, I’d suggest to test latest code first, so build from the master branch.
I am adding the maintainers to Cc. Maybe they have an idea.
Kind regards,

Hi Mahmut,
I no longer work on this, don`t known current code status and can`t check if it is related to your issue or not but from your log:
[INFO ] SF: Detected 00 0000 with sector size 0x1000, total 0x1000000 [ERROR] SF size 0x1000000 does not correspond to CONFIG_ROM_SIZE 0x800000!!
When I last worked on this board CONFIG_ROM_SIZE should be set to real/physical size of your flash chip (guessing 0x1000000 = 16M) And CONFIG_CBFS_SIZE (writing from my memory) to expected coreboot image size i.e. 0x800000 (8M)
After building it will give you 16M image then you need to extract coreboot part (last 8M) and flush it to top of flash address space (or use other methods to build full image)

Hi, The log show x86 exception 18 which is a "Machine-check exception". This exception indicates a unrecoverable error found in your hardware.

Hi,
Thank you for your answer.
How can we understand which part of the hardware it is originating from?

I can just give very general guidance because I'm out of this project for long time.
Basically machine check means that something seriously went wrong. Possible causes:
1) ECC memory errors/misconfigured memory setup 2) PCI resource allocation problem (e.g. something overlaping I/O apic area) 3) CPU erratum - I remember some CPU suffer from fake machine check exception 4) system memory map wrong?
To figure out what went wrong, you need to print out the machine check registers. Every CPU model has different amount of register banks. You will likely need to patch the handler to print it in there, or use some kind of hardware debugger.
For details for machine check and the registers/possible causes - look for "CHAPTER 15 MACHINE-CHECK ARCHITECTURE" in Intel 64 and IA-32 Architectures Software Developer’s Manual Volume 3 (3A, 3B, 3C & 3D): System Programming Guide
Also handy chapter is "INTERPRETING THE MCA ERROR CODES"
Thanks, Rudolf

Another source of inspiration is drivers/edac/ in the Linux kernel source.
