Will be testing this RSN. Can you provide more information on where you think you are getting the GSF values from? I am not aware of such information. The internal documentation always only refres to the minimum VID/FID values from the MSR. Also, according to the specifications of all C7 models listed, there are some that require a minimum of 400MHz, others require a minimum of 800. I have not found any that would require a minimum of 600MHz. So I don't really know if your system really operates outside any specified range. The only thing I know of that you can read from the CPUID vendor string is the maximum clock frequency in ASCII. So it seems, e_powersaver is not really at all as dangerous as it appeared! -- - Harald Welte http://linux.via.com.tw/ ============================================================================ VIA Free and Open Source Software Liaison -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
