Bug 481306

I have an Acer Aspire 5920, with a Core 2 Duo and excactly the same thing happens to me too. An ugly way to get around this is to pass "nosmp" at kernel options, but you sacrifice one cpu.

This is not a unique problem on fedora. It also happens on Fedora 10 beta, Mandriva 2009.0, Mandriva 2009.1 Beta and mandriva's kernel-linus-2.6.29-git5 (which is supposed to be vanilla). As can recall not to have any problems with Fedora 10 Alpha, and Fedora 11 Alpha boots fine also.

In the past I had tried nolapic with success, only to find out that when nolapic, nosmp is implied.

It's a very strange error, and i don't have any other way to describe it. I forget to mention that in my case at least, the laptop works normally except display which is left on "ready." with cursor blinking. I can hear the cdrom reading and i'm certain the os is loaded because the brightness of my backlight changes and if i press power botton, the machine shuts down after a while. I can even read /var/log/messages afterwards.

Currently i don't have a fedora installation, but the logs shows nothing. The only difference was that in case of smp timer used IOAPIC while when nosmp it uses PIC.

Oh, and also once in a while it may boot normally, but i cannot understand when. It just happens to confuse me while i'm trying to find the correct boot options. So far i have failed with:
- clocksource=pic
- clocksource=jiffies
- idle=poll
- nolapic_timer
- mtrr=off
- nohz=off
- highres=off
- pci=nomsi
- pci=noacpi

Try the "nohpet" boot option...

No luck. nohpet failed too.

I was able to get my Optiplex 320 to install using hpet=disable pci=nosmi textinst but now it won't boot. I'm guessing it has to do with the Grub bootloader issue. One step at a time...

Did you try booting with the kernel parameter acpi=off (disables SMP ... this is the more aggressive option) or acpi=ht (does not disable SMP)? I was getting the same symptoms on current Rawhide on an Optiplex 760 and either one of these parameters allowed the machine to boot normally.

Optiplex 320, latest BIOS 1.1.12. Only acpi=off works for me. Fedora 11 boots fine but I need Fedora 10 in this case.

This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  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bug reports from releases that are no longer maintained.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 '10'.

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 10'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 10 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 to the applicable version.  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.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

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

Thank you for reporting this bug and we are sorry it could not be fixed.
