V310-15ISK bug in BIOS!

Hi!

BIOS version is latest (0ZCN26WW)

I've tested two V310 laptops. Both have the same errors (in varios Linux distributives), like:

 

TSC synchronization [CPU#0 -> CPU#1]:
Measured 4580324345 cycles TSC warp between CPUs, turning off TSC clock.
Marking TSC unstable due to check_tsc_sync_source failed

It points to CPU microcode errors or another errors in BIOS.

 

Unfortunately at lenovo site no possibility to download prior version of BIOS to check what version without this bug.

 

So, before to releasing new BIOS version, I want to warn people who need correct TSC work about this laptop - this error can be fixed only in BIOS, not in service centre!

 

BR,

Evgeniy
