Description of problem: Since some undetermined kernel update. I have this message when booting. Something went wrong with powernow-k8 that makes the cpuspeed daemon to fail to work as usual. (the daemon cannot be started) Version-Release number of selected component (if applicable): The problem have been experienced with [root@kwizatz F-7]# rpm -q kernel kernel-2.6.23.15-137.fc8 kernel-2.6.24.2-7.fc8 kernel-2.6.23.14-115.fc8 kernel-2.6.24.3-13.fc8 I also tryed to downgrade cpuspeed, but it seems not be related to it. (at least I thought it was working previsouly with an older kernel , I'm still searching for lastest older kernel that works. ) How reproducible: always Steps to Reproduce: [root@kwizatz ~]# service cpuspeed start [root@kwizatz ~]# service cpuspeed status cpuspeed is stopped [root@kwizatz ~]# service cpuspeed stop [root@kwizatz ~]# Actual results: cpuspeed cannot be started, and no message tells it has failed to load. It probably fails around this: [root@kwizatz init.d]#cat /sys/devices/system/cpu/cpu0/cpufreq cat: /sys/devices/system/cpu/cpu0/cpufreq: This file doesn't exist [root@kwizatz init.d]# cat /sys/devices/system/cpu/cpu0/[tab] cache/ crash_notes topology/ Expected results: cpuspeed should be allowed to start If powernow-k8 isn't failing to work. Additional info: since 2.6.24's kernels I also have this message: pnpacpi: exceeded the max number of mem resources: 12 No bios updates are currently available for this workstation. (last is V 1.D from 01/29/2007) MotherBoard is MSI K8N neo2 Platinum. (s939) dmesg dmidecode and /proc/cpuinfo are comming soon.

The system BIOS doesn't support dual-core processors. There is nothing we can do about that.
but the initial report suggests that this worked once ? This means ACPI has regressed, and we're falling back to the PSB.

Apparently I have this problem since the F8 "gold" kernel (kernel-2.6.23.1-42.fc8), and maybe earlier... I will try to re-install FC-6 or F-7. On the other side I hope to have a newer bios from MSI but... well, I will see.. For now. I have the most current bios available, and indeed I have upgraded from mono to dual-core processor.
ah, in that case F6/F7 likely won't help either. Sounds like the "powernow for >1 cpu" acpi tables are missing entirely. It's likely only a bios upgrade can save you.
OK the problem disappeared when i entered the bios and figured out that "cool & quiet" was desactivated - (I've also switched from S1 to S3). Now I it can run cpuspeed: [root@kwizatz ~]# service cpuspeed status Frequency scaling enabled using ondemand governor Sorry from this wrong report - I haven't thought the message could be linked to an option that can be activated/desactivated from the bios.
This might not be as easy as expected. I've experienced a freeze (at least with kernel-2.6.24.3-13.fc8 ), when cool & quiet is re-enabled. and I haven't experienced such freeze since much time. I think I may have disabled C&Q because of that. Which may indicate a bios problem. For now, and kernel-2.6.23.15-137.fc8, everything seems fine... let's see.
