Description of problem: Version-Release number of selected component (if applicable): 1.2.1-1.33 How reproducible: always Steps to Reproduce: 1. Install Fedora Core 5 2. Boot 3. Crash Actual results: System crashes right after CPUSpeed has been launched, rapidly flashing small graphical glitches appear on the screen if rhgb is disabled, otherwise just freezes Expected results: System boots normally Additional info: This occurred on an fresh Asus A8N-VM CSM mobo, Athlon64 3200+ (Venice), software raid-1. The kernel option acpi=off was used (wouldn't get past udev without it). The workaround was to uninstall cpuspeed completely. I was able to boot normally after that.
I have experienced a very similar issue the past two days in my attempt to install FC5. I am using an ABIT AV8 mobo, Athon64 3200+. The systems was operating fine for months running FC4 x86_64. Before attempting to install FC5 I added 1G ram to bring the system from 1 to 2G. I imediately started getting intermittent kernel panics in FC4, always related to cpuspeed. Attempts to install FC5 always hung at the last rpm xorg-x11-drivers. I couldn't figure out how to disable cpuspeed for FC5 install, but managed to disable cpuspeed and manually configure FC5. Disabling cpuspeed using "chkconfig cpuspeed off" on FC4 seems to have eliminated the panics for FC4. This issue did not start until I moved from 1G to 2G of RAM. And yes I did run memtest86+ successfully after the RAM upgrade.
I believe the original poster's problem was largely a bios issue, resolved by the latest bios for the a8n-vm csm. I've got that exact board w/the latest bios and an Athlon 64 3500, and cpuspeed works perfectly with it under FC6 (and previously w/FC5 as well). Not sure what's up w/the Abit board... Please feel free to open a new bug if the latest cpuspeed is still failing on that system.
