    Marking TSC unstable due to TSC halts in idle

    seanyoung

      Hello,

       

      I used to have a DG33TL motherboard which run linux without any problems. The rdtsc instruction worked fine -- the kernel never reported any stability issues, so I could use it as a great way of measuring how fast routines are.

       

      Now I upgraded to a DG45ID motherboard for a faster GPU (same memory, same CPU). Now I get:

       

      Marking TSC unstable due to TSC halts in idle

       

      While booting linux. Now I'd really like to be able to use rdtsc. Is there anything I can do prevent this from happening?

       

      Also, how bad is this?

       

      The CPU is a Q6600 and I have 8 GiB of RAM. Problems seem to ocur on all kernel versions I tried.

       

      Thanks,

      Sean
