Fixing error message “Failed to access perfctr msr”

Regarding: Failed to access perfctr msr
This is a notification that the CPU does not support performance counters. These are only used to help the OS detect hanging (NMI Watchdog) and for PMU based performance analysis. This can be ignored.
Regarding: Fast TSC Calibration Failed
This can also be ignored.

Add “clocksource=tsc” to grub

sudo mousepad /etc/default/grub
