Red Hat Bugzilla – Bug 251443
Cannot boot without pci=noacpi
Last modified: 2009-07-14 14:03:27 EDT
Description of problem:
I can't seem to boot without passing the maxcpus=1 kernel argument at boot time.
Any attemp to boot without the argument results spews some error messages
starting with ata1.00(pics attached), which later leads to ata2.00 errors.
Version-Release number of selected component (if applicable):
Current kernel version (uname -r): 22.214.171.124-41.fc7
But I remember having to do this for all F7 kernels since installation.
Steps to Reproduce:
Boot1.jpg in the attached pics show some BIOS bugs which I'm not sure are
related to the current issue.
Boot[2-4].jpg show the error messages I get after booting without the kernel
Let me know if you need any other information.

Try some of these options instead of maxcpus=1:
Thanks for the quick response...I tried all of the suggested options. Only
"pci=noacpi" seems to work without any noticeable side effects.
With both "pci=nomsi and "pci=nomsi,nommconf" got stuck at the login prompt (tty
). But I was not able to login. The cursor blinked but no input was being accepted.
With "nolapic_timer" and "nolapic" options, I was able boot fine both times. But
I saw some strange keyboard/mouse behavior with the former option and with
"nolapic" /proc/cpuinfo showed only one cpu (even though I did not specify
I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.
I am CC'ing myself to this bug and will try and assist you in resolving it if I can.
There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?
If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.
Yes, I still have the problem with the latest F7 kernel. But I'm using
"pci=noacpi" instead of maxcpus=1. Let me know what info you need to resolve
If you could test with the Fedora 8 Test 2 live cd that would be appreciated as
at the moment we are trying to squash bugs that prevent a successful install.
You can get it from:
It may also tell whether this has been fixed upstream. If the issue still exists
with F8 Test 2, I will attach a blocker bug and assign to the relevant maintainer.
I tested Fedora 8 Test 2 and the problem still exists. I cannot boot without
pci=noacpi kernel argument (see attachment (F8T2-BootRegular.jpg). There were no
error messages though (I left the machine for 30 min).
I could boot into runlevel 3 when I added the kernel argument but I could not
start X. For some reason the display was garbled (see attachment
F8T2-Boot"pci=noacpi".jpg) and it hanged. I tried both radeon and ati drivers.
This at least confirms that the current problem is not fixed in the newer kernel.

Apologies for not getting back to you sooner. Was this resolved for F8 release?

No. I still have problem booting without pci=noacpi with latest F8 kernel update
Can you post the output (as a text/plain attachment) of:

Output of dmidecode as requested...
You might want to try a BIOS upgrade which is available (with the usual caveats) at:
If you dual boot then you can perform this under Windows, if not:
Let me know how you get on.
Any update on this?

I did try the BIOS update as you suggested but there was no change. I still have
the issue in 126.96.36.199-137.fc8.
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:
The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This issue is still present in Fedora 9. I tried Live KDE CD and could boot only
with "pci=noacpi" as a kernel argument.

Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
