kernal: Hardware error. Is this something I should be worried about?

[Darqfallen]

Was casually browsing my logs this morning and noticed this error pop up

 

Jan 21 03:57:59 Dirge kernel: mce: [Hardware Error]: Machine check events logged
Jan 21 03:57:59 Dirge kernel: [Hardware Error]: Corrected error, no action required.
Jan 21 03:57:59 Dirge kernel: [Hardware Error]: CPU:0 (15:2:0) MC4_STATUS[-|CE|MiscV|-|AddrV|-|CECC]: 0x9c1f4850001c017b

Jan 21 03:57:59 Dirge kernel: [Hardware Error]: cache level: L3/GEN, tx: GEN, mem-tx: EV

CPU temps are within norms so I am a little concerned.

Should I be?

Most likely a bad CPU.  It's L3 cache reported an ECC error, which was corrected, but all mce errors should be taken seriously

Verify the temperature of the processor and that it isn't overclocked.

[Darqfallen]

Verified as not overclocked. CPU temps are in the 45-55C range

Then I would suspect one of:

- faulty processor

- incompatibility with the dynamic power-control of the current kernel

- unclean power from the PSU

[Darqfallen]

Processor has been running for 12 months+ with no issue so far, so I don't think its a faulty processor.

Perhaps the PSU has gone bad, I will wait to see if more errors creep up.

Since I've only updated to 6.4 four days ago I'm leaning towards:

I will monitor and keep you guys updated.
