Red Hat Bugzilla – Bug 166741
Boot process hangs at CPUSPEED step on x86_64

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).
Boot with cpuspeed enabled, this always crashes.
Steps to Reproduce:
1. Boot the system into fc4.
Crashes early in boot process (while starting pcmcia).
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
