Namespace lookup failure error on QuadCore E5420

[Peter Strazovec <bubak@xxxxxxxxxxxxxxxxx>]

I have problem with Namespace lookup failure error on E5420. 
( ACPI Error (psargs-0358): [CS03] Namespace lookup failure, AE_NOT_FOUND )
Thus acpi not functional (cpufrequ via p-states, etc...).

Does anyone know about some patch or some hint?

CONFIG_ACPI_DEBUG=y, CONFIG_ACPI_DEBUG_FUNC_TRACE=y,
dmesg, interrupts and cpuinfo attached.

thanks
Pete
