Hi,
this is my first time posting here and it is quite possible that I've overlooked something obvious. In that case please just point me to whatever I should have read and accept my apologies.
On my ThinkPad T430 running Coreboot-4.8.1 as part of an Heads install, I see these error messages when turning on the PC:
mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank: 7: ee20000000 3110a mce: [Hardware Error]: TSC 0 ADDR fefe78c0 MISC 3880000086 mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1622589409 SOCKET 0 mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank: 8: ee20000000 3110a mce: [Hardware Error]: TSC 0 ADDR fefe7880 MISC 3880000086 mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1622589409 SOCKET 0 APIC 0 microcode 1f
I do not think it is an issue with the actual RAM:
[i7-3520M] [2x8GB Silicon Power Hynix] ... no error [i7-3632QM] [2x8GB Silicon Power Hynix] ... mce errors
[i7-3520M] [2x8GB Crucial] ... no error [i7-3740QM] [2x8GB Crucial] ... mce errors
While looking at this (but for other reasons) I replaced the original i7-3520M with a i7-3632QM and then went back to the original before ultimately settling with a i7-3740QM. I also went through three different sets of RAM, one of them obviously corrupt so I didn't even include it above.
All this is to say that the above and some searching leads me to think this might be more of a software / timing issue maybe -- but I am far out of my depth. Hence my asking here for ideas and pointers what to do next.
Thanks & Cheers, /Sven
