I really don't know anything about ACPI or these tables, but they look corrupted. It seems that you have an entry for a 25GHz CPU... I'm CC:ing the cpufreq list, since someone there might have better suggestions. cpufreq folks: Frederik has a Tosiba M30-851 laptop with this CPU: vendor_id : GenuineIntel cpu family : 6 model : 13 model name : Intel(R) Pentium(R) M processor 1.50GHz stepping : 6 cpu MHz : 1496.370 flags : fpu vme de pse tsc msr mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe tm2 est bogomips : 2957.31 In theory the ACPI tables should work fine for this Dothan, but they seem corrupt. It seems that centrino_cpu_init_acpi() is getting a 0xffff control register value, and a corresponding 25GHz CPU core speed. I'm assuming there's someone who knows what this means. J
