Hi!
  I am using vanilla kernel 2.6.8.1 + acpi-20040715-2.6.8 on Toshiba 
A30-303 - P4 3.06 GHz. Everything seems to be OK, but in dmesg I have this:

ACPI: Processor [CPU0] (supports C1 C2, 8 throttling states)
acpi_processor-2250 [50] acpi_processor_get_inf: Error getting cpuindex 
for acpiid 0x1

It's something important?

PS: same mesage with 2.6.7 + acpi-20040715-2.6.7
