The CPU is a 1.8Ghz mobile P4. 2.5.56, you say... let me check... yep, then this patch is missing (it's in 2.5.56-bk). Could you send me a /proc/cpuinfo, please? Especially if this patch doesn't work :) Dominik diff -ruN linux-original/arch/i386/kernel/cpu/cpufreq/speedstep.c linux/arch/i386/kernel/cpu/cpufreq/speedstep.c --- linux-original/arch/i386/kernel/cpu/cpufreq/speedstep.c 2003-01-10 21:55:28.000000000 +0100 +++ linux/arch/i386/kernel/cpu/cpufreq/speedstep.c 2003-01-10 22:13:33.000000000 +0100 @@ -447,7 +447,7 @@ if (c->x86_model != 2) return 0; - if (c->x86_mask != 4) + if ((c->x86_mask != 4) && (c->x86_mask != 7)) return 0; ebx = cpuid_ebx(0x00000001); - 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/
