Description of problem: This bug is essentially the same as bug #158523, but I'm reporting it as new since I'm using fc4, not fc3. I tried to install fc4 on a brand new computer with no other operating systems; it is a dual Opteron 244 system with a TYAN K8WE 2895 mainboard. The install process works fine, but the kernel always crashes while starting the pcmcia daemon during the boot process. A "kernel panic" message and some C code appears before the screen goes blank. By entering interactive mode, I found the culprit was actually the cpuspeed daemon. After turning this off, the system booted successfully. I then logged in as root and disabled cpuspeed. After making this change, the system boots successfully every time, and seems to work okay. Version-Release number of selected component (if applicable): fc4 (DVD media purchased from linuxcentral.com this week, I don't know the release number off hand, or if there is one). How reproducible: Boot with cpuspeed enabled, this always crashes. Steps to Reproduce: 1. Boot the system into fc4. Actual results: Crashes early in boot process (while starting pcmcia). Expected results: Successful boot. Additional info: Crash occurs only when cpuspeed is enabled. Will disabling cpuspeed have any adverse side effects on my computer?
Please try the latest errata kernel from updates-testing, this has a powernow-k8 fix that could fix your problem. (Though its hard to say, as you didn't include the backtrace).
