I don't know what I'm looking for but there are 2 things that I
noticed about the contents of the /proc/interrupts file:
1. when I typed 'cat /proc/interrupts' I got a message saying
something like 'file not terminated correctly'. I don't remember the
exact wording. It looks like a few characters and the end-of-line are
missing. I'm guessing that this is no big deal and that cat read the
file in the middle of an update.
2. The LOC line has some large numbers; ~1500000 for each processor.
This is immediately after boot up, (Immediate isn't the right word as
it takes ~45mins to boot and log in) Is this normal?
I have updated to FC7T4 and I am now running the 2.6.21-1.3116 kernel
which someone suggested would correct the problem but it did not. I
have also tried with acpi=off as a kernel option but that didn't
change anything either.

Nothing about timeouts. Here are a few things from dmesg that might be
of interest.

How to prune out old rpm files from fedora repository?
by Paul Johnson
I run a server that has updates of RPMs I build for our lab. The
packages directory is getting too big and fat with 10 or 15 versions
of some RPMS. I wonder if somebody has a script that can clean out
the older versions? Something that cooperates with the createRepo
script?

"Error while initializing sound driver": 2 out of 4 restarts.
by A.J. Bonnema
Hi All,
Running Fedora Core 6 (updated) I run into regular sound problems.
I would be very grateful if someone could point me in the right direction.
I include as much information as I can below.
If you need anything else, please specify.
I am quite willing to try different things, but I have no idea
===== Symptom ======
Every time I restart the machine I have to wait whether I can play my
music or not.
2 out of 4 times I get the above error message, complete it is:
=== Error message ====
"
Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (No such file or directory)
The sound server will continue, using the null output device.
"
I get this message in a window after KDE starts.
======= Device =============
When I then start (from the GUI) the menu options
"Administration/Soundcard Detection" I can see the chip is being
detected (nvidia Corporation CK804 AC'97 Audio Controller, module
snd-intel8x0), but the PCM device is empty (in both tabs "Sound test"
and "settings").
========== Sound log file ============
Under the tab "System" I can push a button called "Generate sound log
file /root/scsconfig.log". I included this file as attachment. If this
doesn't work I will send a second mail containing the contents (but it
is a large file....).
I am running Fedora core 6, updated to the current version.
Can someone point me in the right direction?
Guus.

Re: FC6 kernels & 4GB of memory
by Darryl
Quoting "Wolfgang S. Rupprecht"
>To see your memory layout check /proc/mtrr.
Ok, this is from 32bit PAE kernel:
$ cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg01: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
reg02: base=0xc0000000 (3072MB), size= 256MB: write-back, count=1
reg03: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=1
> reset to factory "optimized" settings.
Did that after the last BIOS update.
> select mtrr discontinuous (was contigious)
That option disappeared with a BIOS update actually. a new one popped up
regarding Virtual stuff though.
> select mtrr hardware mapping (was disabled)
> select iommu 128k (was disabled)
BIOS doesn't have those options.
I tried downloading the latest/greatest 2.6.21 kernel and compiling my
own 32bit "PAE" & "regular" kernels but they did the same thing.
"regular" sees all the memory but tells me to use a PAE kernel and "PAE"
won't use all the memory and crashes on boot without mem=4095m. A
little frustrating since the "regular" kernel and memtest86 see all the
memory. The good news is that the on-board NIC is natively supported in
.21 though :-/

firefox bookmarks
by Richard E Miles
Is it possible to save the firefox bookmarks so that when I do a clean install
of FC4 I can reload them?
I tried to cp the bookmarks.html file back into the /home/rmiles/.mozilla/firefox/0qem39dn.default directory but it did not
restore them from an earlier saving of this file.
It would be nice to be able to reset the bookmarks that I had in FC 3 to the FC 4
firefox.

How to find total MB of a directory plus all subdirectories
by Nigel Henry
This is a silly question perhaps. I have my soundfiles in a directory named
Sounds Library, this contains many subdirectories, which contain the .wav
files.
What command can I use to find out the disk space this directory is taking up,
including all the files that are in the subdirectories?

FC LDAP server
by Chris
Forgive my ignorance on this topic - I would like to build an LDAP
server at our shop. We a native 2k3 domain and would like this FC LDAP
server to pull in all the info from AD. Then periodically, have the FC
server sync with new addition/subtractions of AD.
Is there a How-To out there somewhere that someone can point me to?
I don't want to recreate the wheel by hand-inputing information into the
FC LDAP server.
TIA and thanks for the patience and understanding.

Public keys - again.
by Anne Wilson
Realising that I hadn't installed lshw since I installed FC6, I tried to get
it today and came up once again against the public key problem. I'll never
get the hang of this :-( I followed the link on freshrpm's web page and
saved the file, then ran 'rpm --import path/to/file' which appeared to put it
into the right place, but still the package wouldn't install because it said
there was no public key. Wondering whether the problem was because something
was broken in my repo setup - out of date, perhaps - I removed the repo and
reinstalled it. Still no joy. Just what is it that I have forgotten?

Dependency problem (faad2) with ffmpeg-libs
by Jeroen Lankheet
Hi,
I can't update my FC6 machine anymore because yum complains about:
--> Populating transaction set with selected packages. Please wait.
---> Package ffmpeg-libs.i386 0:0.4.9-0.37.20070503.lvn6 set to be updated
--> Running transaction check
--> Processing Dependency: faad2 < 2.5 for package: ffmpeg-libs
--> Finished Dependency Resolution
Error: Missing Dependency: faad2 < 2.5 is needed by package ffmpeg-libs
after doing a yum update.
First of all, yum also rejects updates that are not depending on this
error, I think that's a nasty feature 'we' should get rid of.
So how can this be fixed?
I have installed the faad2-2.5-7.fc6.at rpm
Thanks,
Jeroen.
