 |
|
Hello,
In startup boot log, I get a print "need dbus" as you can see here:

I am not sure what it means, and if it is some error that should be fixed.
What does it mean ?
Regards,
ranran

dbus started according to the pic, but you do have a problem with your microcode or the processor (might be wrong selection in kernel) see mce error at top of pic.

Hi
thank you.
So I will ignore the 'need dbus' message.
As to the hardware error mce:

What should I do ? I haven't found a lot of info on this.
Thank you very much.

What processor do you have and what's configured in the kernel?
And do you have firmware emerged?

This might be bad memory, I would try reseating it or ensuring all the sticks are of the same specs.

I have com express , conga-ma5, with atom apollo lake.
https://www.congatec.com/fileadmin/user_upload/Documents/Datasheets/conga-MA5.pdf
So, I assumed it was already well checked before being sold by congatec.
Maybe the kernel which I am using 4.14.5 (which was installed with gentoo) does not contain the required configuration of microcode ?
I think congatec provide yocto which should be used with conga-ma5.
by the way, everything seems to work fine (just having this error in startup....)
Thank you for any idea,
Ran |

I know nothing about the conga/atom stuff. So my help will be limited.
But as Bunder said above it could be that you have a bad memory or an incorrectly seated memory.

Apollo Lakes can be weird, check that you are running latest BIOS. Try with "clocksource=hpet processor.max_cstate=1 intel_idle.max_cstate=0" boot options.
| Code: | CONFIG_X86_MCE=y
CONFIG_X86_MCELOG_LEGACY=y
CONFIG_X86_MCE_INTEL=y
CONFIG_X86_MCE_THRESHOLD=y |
I have these MCE features enabled in kernel. |
