MSR 0xcd, which is MSR_FSB_FREQ. One hacky fix is needed. You seem to be in the same situation as mine there, quick glance at your CPU ID makes me think it reports model 0xc too: http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/src/sys/arch/x86/x86/intel_busclock.c?rev=1.11&content-type=text/x-cvsweb-markup I asked for a pull-up about a week ago, so should come in eventually. Try patching around as I did. Cheers, -- Jean-Yves Migeon [email protected]
