missing acpi component file in 1653
Last modified: 2015-01-04 17:23:47 EST
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050923 Fedora/1.7.12-1.5.1 Description of problem: upgrade kernel on Dell I7500 laptop, through YUM-X. on boot-up with 1653, i see an error message similar to: "...missing file acpi_cpufreq.ko" this component file exists for versions 1456 and 1644 on the same machine. also, the component file did get installed for version 1653 on a Dell PW410 machine (PW410 is dual processor). Version-Release number of selected component (if applicable): kernel-2.6.14-1.1653_FC4 How reproducible: Always Steps to Reproduce: 1. boot to 1653 2. see error message on-screen 3. Actual Results: no obvious problem so far, on usual use of the machine. Expected Results: it seems that 'acpi_cpufreq.ko' was installed for two previous versions, so i expect it should have been installed on upgrade to 1653. Additional info:
I've no idea what 'yum-x' is, but that's my suspect right now, as this is the only report of this bug, and that file is installed on every one of my test boxes fine. can you try.. rpm -e kernel-2.6.14-1.1653_FC4 yum update kernel
'yum-x' == my shorthand for "YUM Extender", sometimes known as "YumEx". it's the GUI-based version of Yum. i'll spell it out next time. meanwhile... ran 'rpm -e', then 'yum update kernel'. same result. i don't find the full error message in /var/log, but at boot-up the line reads: "FATAL: error inserting <path to file>acpi_cpufreq.ko, no such device" so far, i don't find any other problem with machine operation. i don't know what this file is or should do. it did get installed in previous kernel versions, so unless there is a change i suppose i could simply copy the 1644 version to the 1653 path, but i'd prefer to understand why it's dropped or ignored during update. for what it's worth, from Google: Results 1 - 9 of about 25 for acpi_cpufreq.ko +error. (0.75 seconds)
i spent a bit more time on this. after the 'rpm -e'/'yum install' exercise, i now find the 1653 version of acpi_cpufreq.ko on the system. however, there is still a "fatal" error message on boot-up, immediately following a "Checking for new hardware" line. if i boot to 1644 instead, there is no error message. just for grins, i ran 'updatedb', no effect. so, it seems the file is present, but i get an error message on boot. up to now, i still don't find a system problem that i can attribute to this device file and don't understand why there was no message for 1644 and earlier but there is one now.
i decided to try acpi options for 1653. now, i find that if i set acpi=off, there is no error message on boot-up. my guess is some combination of: a. there is some kind of problem in acpi_cpufreq.ko for 1653, but not for 1644 or 1456, or... b. the component file is fine, but there is some problem in kernel 1653 (acpi appears to be causing some kind of problem in 1653 SMP. are the two conditions related?) c. the component file is fine, the kernel is fine, the feature was disabled in earlier versions; that's why it looks like it's now broken. lastly: bad guesswork, all of the above. it's something else.
in previous kernels there was a check in the ACPI code for a BIOS with a manufacture date of '2000' or earlier. If we found the date was <= 2000, we disabled acpi. The latest update disabled this check, as it's believed that the acpi interpretor has got better with age, and a lot of things that were previously thought to be bios bugs were in fact, kernel bugs that are now fixed. It turns out that there's a few rough edges here and there that still need fixing up. The good news is that the acpi-cpufreq message is just a harmless warning. I'll be pushing out a cpuspeed update for fc4 soon, which should make it go away.
ah! ...so, some of my guesswork was close, after all. i do recall seeing some message about "<=2000" on boot-up, in earlier versions. i had ignored that up to now. thanks for the update. i'll just look for the later release.
