Description kirk 2018-05-02 00:47:11 UTC

Hi everyone,
my apologies for the disturbance.
I've been getting these errors on boot. The hardware is brand new and also I've tried different linux distros. All of them had in common the same kernel version.

The errors that I see upon boot are the following:

<<<

Rolling back the kernel to version 4.9.x removes some of the errors but. For instance I don't see anymore the [Firmware Bug] but the errors related to ACPI they still appear at boot time.

I am not sure but I think these errors might be kernel related since rolling back the kernel version does reduce the amount of errors showing upon boot but then again I'm not a kernel expert!

Thank you in advance for your time and support!

Kind Regards,
Kirk.

Please confirm the ACPI ERROR messages are gone if you boot with kernel parameter libata.noacpi

Comment 2 kirk 2018-05-02 12:55:33 UTC

@Zhang Rui,

Thank you for the prompt reply. The only thing that has been removed is the [    0.004000] [Firmware Bug]: TSC ADJUST differs within socket(s), fixing all errors.

Everything else still remains unchanged.

Here is a diff between previous errors and errors after booting with "libata.noacpi" parameter.

Hi Zhang,

thanks for getting back to me.

I've attached the acpidump output as requested.

Please let me know if you need anything else.

Regards,

I have checked your ACPI dump, the ACPI errors are complaining a firmware bug, but it is harmless.
And I believe the TSC errors are firmware bug as well.
Give that all the errors are either harmless or have already been handled in kernel, I will close this bug report.
Please feel free to reopen it if you observe something malfunction.
