last 2 kernels fail on Asus M2N68-VM

Nothing in bios updates dmesg gives
[ 4.374743] [Firmware Bug]: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands. Please report this to the Linux ACPI maintainers and complain to your BIOS vendor.
what next?

Nothing in bios updates dmesg gives
[ 4.374743] [Firmware Bug]: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands. Please report this to the Linux ACPI maintainers and complain to your BIOS vendor.
what next?

The error message is because your BIOS does not have a correctly configured ACPI _PSS (Performance Supported States) object. Section 8.4.4.2 of the ACPI specification states that this is an optional ACPI object that indicates to operating system the number of supported processor performance states that the system can support.

The _PSS object is essentially a list of information about available performance states including internal CPU core frequency, typical power dissipation and the control register values needed to transition between performance states.

It's worth contacting the BIOS provider and/or ASUS and reporting this as a BIOS issue. Also it's worth contacting the Linux ACPI maintainers (<email address hidden>).

Is this problem causing your kernel not to start?

flashes ntp and unable to log on

The bios updates do not seem to address any problems but there is a
linux driver for sound.
from observations the text starting up shows and then the display
pulses, can read the start of ntpd and stop ntpd followed by a term
logon prompt but display pulse inhibits login or any further action.
what log files should I send that would help unravel this?
