i have the same messages:Clocksource tsc unstable (delta = -293719238
ns)

i find this in internet:

"TSC=Time Stamp Counter. Processors have dynamically changed clock speed (ofc 
to save power). The TSC is supposed to tick at the CPU rate (unless it's a 
constant_tsc, see /proc/cpuinfo flags, so on frequency change, this ought to 
happen. The kernel will automatically switch to something else. There's acpi_pm 
<-(this is what yours has switched to) and, IIRC, pit. This message seems to 
appear with the newer kernel upgrades."
Check you have installed another clock source like acpi_pm

cat /sys/devices/system/clocksource/clocksource0/available_clocksource

You can try adding the below to your kernel command line. This won't get
rid of the unstable line but it will force the kernel to use a more
stable clocksource so there should be no trouble switching over anymore
(if indeed there is trouble to begin with).

clocksource=acpi_pm (or hpet)

I will make probe but in moment i must see how cann type this command for grub2.
Please the post the results.
