4th June 2008, 11:41 AM
I have a Hp dv2760el with F9 X86_64 with the last upgrades. System works well, it is fast and stable but i have a big problem with che cpu scaling.
I have looked log file after trying to start cpuspeed service (that doesn't starts) and the error is as follow:
Jun 2 19:15:26 pc0x2 kernel: ACPI Error (psargs-0355): [\_PR_.CPU0._PSS] Namespace lookup failure, AE_NOT_FOUND
Jun 2 19:15:26 pc0x2 kernel: ACPI Error (psparse-0537): Method parse/executionfailed [\_PR_.CPU1._PSS] (Node f7b451b0), AE_NOT_FOUND
Jun 2 19:15:26 pc0x2 kernel: ACPI Exception (processor_perflib-0255): AE_NOT_FOUND, Evaluating _PSS 
This is the complete output of "cat /var/log/messages | grep ACPI"
I hope anyone of you can help me beacuse this problem cause a high cpu temperature and low battery duration :(
Thanks in advance and sorry for my very bad English

Ok, there is a bios upgrade to solve my problem.
Now my question is: How to install the upgrade ( with a winlash utility ) from fedora without reinstall windows? Anyone knows a method?
Thanks very much :)

Thanks you for your reply, now i look if this tool can manage winflash packages but i'm afraid to have to reinstall windows in order to safely flash the bios :(
