Description of problem: On Dell Inspiron 1501-Laptops during startup the screen presents the message "..MP-BIOS bug: 8254 timer not connected to IO-APIC" right before the Boot-Message "Red Hat nash...". It produces a lot of useless errors like this APIC error on CPU1: 40(40) in the dmesg-output and the /var/log/messages Version-Release number of selected component (if applicable): How reproducible: Run computer Steps to Reproduce: 1. Start and run your machine Actual results: Expected results: Additional info:
Same problem with Fedora8 x86_64 My believe is that it appears earlier on screen: ACPI Error (tbfadt-0453): 32/64X address mismatch in "Pm2ControlBlock": [00008800] [0000000000008100], using 64X [20070126] On Fedora-test-list: Alan Cox wrote: >If you've found an APCI spec bug send a note to Len Brown anyway (you > can file a bug but Len at the end of the day is the Mr ACPI) > <len.brown>. > I sent dmesg files, screen copy, to "len", and the bug may be more serious as at times the error goes undetected ( APIC error on CPU1 doesn't show in log log files, etc. ) //ARNE
This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Personal opinion: the bug-report shows history which may be of value. The bug is present in Fedora 8, and I suspect it will be in Fedora 9.
Changing version from "7" to "8".

Moving to proper component and changing version from 8 to 9 to make sure it doesn't get autoclosed. Regards, Phil
The most common cause of this problem is a misconfigured APIC and most often the APIC is misconfigured before boot (by the BIOS). Can we verify the BIOS is not the culprit? Please verify the BIOS with Linux Firmware Kit. Download the latest ISO and boot off CD. Download from -> http://linuxfirmwarekit.org/download.php Also, can you attach a /var/log/dmesg from the affected hardware?
Closing out due to inactivity. If the reporter is still having a problem in F11 Beta please update the report with the required information from comment #7.
The error is present in Fedora-10, just not announced in the same way. Here is from Fedora-10: ACPI Error (tbfadt-0453): 32/64X address mismatch in "Pm2ControlBlock": [0000880 0] [0000000000008100], using 64X [20080609] ( compare it to Comment #1 )
