Description Vince 2007-09-14 04:36:34 EDT
Description of problem: Anaconda runs extremely slow installing F7 on G33
Chipset (DG33FB board) with 4GB+ of RAM

Version-Release number of selected component (if applicable):

How reproducible: Every time

Steps to Reproduce:
1. Boot to CD
2. Observe first freezes/lag/delay when loading anaconda
3. This persists forever.
Actual results:
 OS takes so long to install, its not worth it.  5 hours before it actually
starts copying files.

Expected results:
 Faster install

Additional info:
 This appears to be the identical bug as # 243835 but this is a different board
and chipset.

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. If you are able to,
could you tell me if you are still having problems with the latest test release,
available from:


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.

I can confirm this issue exists with the Intel DG33TL motherboard, also a G33
chipset motherboard. I have 4GB RAM and I could not install Fedora 7 or Fedora 8
x86_64 without passing the mem=3G argument (mem=4G gives the same result and
same amount of available memory). I'm running the latest kernel
I previously tried Ubuntu 7.10 x86_64 version and it installed and ran fine with
the full 4GB available. I upgraded the BIOS today to version 297 to see if it
made a difference, it did not. There must be some difference between the Ubuntu
and Fedora kernels.

If there is any debug information I can provide or test kernels you would like
me to try to isolate this, let me know. When I say I could not install Fedora 7
or 8, what I mean is that it is so slow booting that it would be a pain to
attempt an install, just like the original bug reporter reported. Limiting the
memory by passing the mem=3G argument allows the install to work fine. Once
installed, the same parameter must be passed via GRUB or the same slow booting
behavior occurs using the normal kernel.

Update your BIOS.
Comment 6 Kent Pirkle 2007-11-15 19:00:41 EST
As I mentioned before, I've updated the BIOS. I'm running the latest version
released by Intel on 10/23/07 - version 297. I don't think its a BIOS issue,
Ubuntu 7.10's kernel 2.6.22 for x86_64 works fine, but Fedora 8 does not.

Hello Kent,

I'm updating the version field to Fedora 8.

After a bit of digging, you might want to try adding:


when booting. Might be related to:

Closing as per previous comment. Please re-open if this is still an issue for you.
Comment 9 Kent Pirkle 2008-02-15 23:23:00 EST
I tried that option already, it did not help.
