CentOS 5 Hardware :: IEEE 1394 HD Access Hang / Slowdown
Dec 9, 2009
I recently added an external hard drive through a IEEE 1394 interface. I'm finding that during large file transfers the system slows to a crawl. It's still running: routing for example seems fine. But running applications are pretty much unusable: Apache is unusably slow, SSH login is very slow, etc. Currently I'm using the IEEE 1394 drivers from Axel's ATRpms but I'm pretty sure I saw this with the default kernel IEEE 1394 drivers too.

I have a Pinnacle IEEE 1394 card which according to Yast/Hardware Information seems to be installed and recognised correctly.
Trying to use Kino to download from a Camcorder via IEEE 1394 nothing happens and looking at Kino Preferences IEEE 1394 tab it tells me:
"The IEEE Subsystem is not responding. The raw 1394 module must be loaded, and you must have read and write access to /dev/raw1394."
I do not have an entry /dev/raw1394 on my system. Files libraw1394 and libraw1394-8 were installed by default(SUSE 11.3 64bit), and I have since installed any others offered which were libraw1394-8-32bit, libraw1394-devel, libraw1394-devel-32bit but to no avail.

I am relatively new to CentOS. I attempted to install 5.3 with firewire several weeks ago and abandoned the install because it was taking too long to figure out the problems. I've had to revisit this and am having troubles with it. I was told that CentOS 5 has firewire 1394 support. When I did the typical install, it didn't physically (manually) install the video1394 and raw1394 modules. At boot up, my computer says that video1394 and raw1394 are "Module(s) not found". If I do <lsmod> I get (*snippet of o/p),
Module Size Used by

dm_mirror 24393 0
dm_multipath 24909 0
scsi_dh 11713 1 dm_multipath

I have found several other posts on the web that indicate I have to get the latest source files, but I do not know which one is the correct one or where to find it. Can anyone ponit me in the right direction? Is there anything else that I need to do?

I'm reading a book on assembly, and it talks a bit about the IEEE floating point format.
Quote:
To summarize, the following steps are used to convert a decimal number to IEEE single format: 1. The leading bit of the floating point format is 0 for a positive number and 1 for a negative number. 2. Write the unsigned number in binary. 3. Write the binary number in binary scientific notation f23.f22 ... f0 2^e, where f23 = 1. There are 24 fraction bits, but it is not necessary to write trailing 0's. 4. Add a bias of 127 to the exponent e. This sum, in binary form, is the next 8 bits of the answer, following the sign bit. (Adding a bias is an alternative to storing the exponent as a signed number.) 5. The fraction bits f22f21 ... f0 form the last 23 bits of the floating point number. The leading bit f23 (which is always 1) is dropped.

I have installed Ubuntu 11.04 64 bit desktop version on ext4 partition without swap. I have maximus iv extreme motherboard with 8 Gbytes RAM. Using 3 internal ntfs formatted hard drives and 3 external ntfs usb 2.0 hard drives.When I am trying to copy or move files FROM or TO any ntfs partiton it is 90 percent chance it is going to freeze.For copy/moving files I am using krusader run as ROOT or as user without root privilege or Nautilus as user without root privilege. It wasn't possible to switch to another terminal - it simply does not react on keyboard or mouse input and only hard reset is possible (scares me because of ntfs disks)From this point of view I have suspicious on ntfs driver but:I am completely beginner in linux and I am looking for help to navigate me how to investigate to find what is causing the problem eventually to solve it?
According to my experience it seems to does not matter if hard disk is internal or external connected through SATA II or SATA III or USB 2.0. I have tried to manipulate with ntfspartitions through the vmware or virualbox or truecrypt software or just do a simplecopy/move files - it have has always the same results - freeze. There is not possible to say how long it is going to work properly and when it is going to freeze - sometimes it's working hour, sometimes it's working couple of seconds - no matter if it is read or write operation/s within ntfs partition.

I'm trying to install CentOS 5.4-x86 on a "new" motherboard, it's an ABIT Fatal1ty AN9 32X. I have a AMD 6000+ Dual Core running stable at 3.01 ghz. 4GB of ram(4x 1GB). nVidia GeForce 7600. 2x SATA II 160GB WD RAID 0 and 2x SATA II 1TB Seagate RAID 0. This setup has been running fine as a FTP server for months and has been flawless for games for about 3 years.Right off the bat during initial install it hangs before loading any GUI.Last lines:
NFORCE-MCP55: IDE controller PCI slot 0000:00:0c.0
NFORCE-MCP55: chipset revision 161
NFORCE-MCP55: not 100% native mode: will probe irqs later

I'm running into what is quite possibly one of the strangest problems I've ever encountered. We recently had a power loss, and some of our vmware instances didn't shut down correctly. Once of those is our Zabbix testing monitor. From that point on, whenever I run the "ll" command, my terminal freezes. This happens over both ssh and the local console. I've forced a disk check via the "shutdown -rF now" command, and it returned no errors. Since ll is simply an alias for ls, I copied ls (and the entire bin directory) from another Centos 5.3 instance, with no change in behavior.

I have just completed an upgrade from 5.3 to 5.4 (64bit) Now when the system starts it gets to Staring udev and then hangs for about 2mins before printing "Timeout" and then continuing.
At various stages during the boot process it just stops with no warning and takes a while to restart.
My boot time in 5.3 was about 50seconds, now with 5.4 it is about 4mins.

My issue is: I am "locked" on kernel 2.6.18-164, I just can't get my server up and running with any later release. It simply hangs at "Starting udev".
The hardware is:
MB: Asus M2N32-Deluxe
CPU: AMD Phenom(tm) II X4 920 Processor
Boot FS: Ext2
RootFS: xfs
RAM: 4Gb
I have 2.6.18-194.el5 running on other machines.
PS: I'm about to install/update a fresh 5.5 disc for testing purpose anyway. I'll update here if it works.

Keyboard Hanging, in CentOS. Some time when I login to Linux or when we come back to use Keyboard after a long time work with mouse, my keyboard will hang for few seconds. I don't know its my USB keyboard problem or another issue. I doubt it started after I install opera browser in CentOS or by VNC setup.

I'm running V5.3 (newly installed) on an FJ E8020 laptop. The problem I have is when shutting down (*not* rebooting). NetworkManager fails to stop and after (during?) the postfix shutdown, the system seems to hang.I cannot access via another screen or remotely. I can't find any clues in the log files.

I have an annoying problem with a 2 nodes cluster that I don't understand.
One of my server is totally shutdown.
When I start cman after a reboot on the other server, it hangs on "Starting fencing...". The process which is actually hanging is : /sbin/fence_tool -w -t 300 -m 45 join
When I start this program manually, I get this output :
# /sbin/fence_tool -w -t 300 -m 45 join
Waiting for all 2 nodes to be members
Waiting for all 2 nodes to be members
Waiting for all 2 nodes to be members
Waiting for all 2 nodes to be members
(and so on...)
What I don't understand is why the fence_tool program wait for the 2nd node to join the cluster and don't fence the other node.
Here is my cluster.conf :
<?xml version="1.0"?>
<cluster name="ctpsrv-bdd" config_version="7">
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="20"/>
<cman expected_votes="1" two_node="1"/>
[Code]....
Would it be a good idea to edit the cman startup script and remove the "-w" option of command fence_tool join, so the command do not hang up ?

I am running Centos 5.5 with all the GUI stuff, including nx server and webmin.Sometimes while watching the bootup messages because my eyesight is very poor.I hit <ctrl s> to pause the output so I can read some details. If I do this late in the init sequence - it often briefly stops the output then the screen disappears under a blue wash (presumably something to do with the GUI login screen ot screensaver??)but the login screen never appears. Also it seems that the script never completes because the imap, webmin and http servers don't appear to have started.
I haven't found any satisfactory way out of it. I can't get back to a console terminal (I've tried ctrl c, d, z, etc.). As luck would have it the nx server has started so I can open an nx session. If I open a terminal in an nx session as root.I can't do a normal restart (shutdown -r now). Nothing happens presumably it can't run the init script because it is still running.The only way I have found to get the system back to life is to run "shutdown -r -n now" in the nx terminal session.There are probably better ways out of this predicament that I am unaware of. Otherwise it is probably somewhere between an annoyance and a bug. I would be interested in any advice the centos "board" may have as to whether this is worth raising as a redhat bug.

I recently bought a Toshiba Portege M200 tablet PC and it's caused me no end of grief to load linux on it. I would like to load CentOS 5.x (because my hosting company uses it and I will be able to learn as I run it).
Here are my resources:
I found internet resources to create a boot disk that enables me to see my 8GB Sony USB flash drive via DOS. It works nicely.
I have a laptop drive to USB converter and can access the hard drive directly from my Win XP desktop. I have PowerQuest's Partition Magic Pro (v8.0) and can make Ext2 and Ext3 partitions at will. I have also loaded a program that allows Windows XP to read and write from Ext2 and Ext3. It works well.
I have tried loading boot images from PXE. This option is mostly out because it seems to be a couple levels past my competency (I haven't been able to get it to work).
Given those resources, what's the best way to load either the CentOS live CD... or some other approach?
Since I wrote this, I figured out how to make a boot floppy that can start an external USB CD-ROM/DVD drive. Here are the files on the floppy:
Here's the contents of my config.sys:
Here's the contents of my autoexec.com:
I can boot to the CD and launch linld.com. The problem is that I keep getting a kernal panic message, saying that a memory block could not be addressed. And when I add the following part to the line above: "initrd=d:isolinuxinitrd.img" the install fails and reboots. I have tried to expand the initrd.img and it appears... blank?

I just finished installing CentOS 5.2 x86_64 on a Dell Dimension 3100 (Pentium 4 with 64-bit support). On the first boot, after completing the final config steps (firewall, SELinux, time server, etc), the boot hangs on "Starting xend:". I have completed a successful installation on another Dell machine (different processor), with the same installation options (I recorded all of the steps and followed them for the second installation).
My boot commands in grub are:
root (hd0,0)
kernel /xen.gz-2.6.18-128.el5
module /vmlinuz-2.6.18-128.el5xen ro root=LABEL=/1 rhgb quiet
module /initrd-2.6.18-128.el5xen.img

This is probably not possible, but just wondering, restarted centos 5.2 remotely, hung at shutdown, kvm'ed to see what was hanging it up, control c'ed and then ctl alt del, just trying to kill the process, was brought back to the login screen, but unable to type anything. Alt-f1 switched to a different virtual console, which was just a blank screen and a blinking cursor, but now able to type things. Want to avoid hard shutdown. Is there anyway to force shutdown/reboot the machine from this console?

I have read all of the articles I could find on the problems. I am using the lilo bootloader as grub doesn't work. I have also added pci=nomsi to my lilo.conf and ran lilo -v. I can get the system to boot with kernel-2.6.18-8.el5. However I can't get the system to boot with kernel-2.6.18-194.11.3.el5.i686.rpm. When I boot with kernel-2.6.18-194.11.3.el5.i686 the system hangs after it prints bios data check successful. I tried adding suppress-boot-time-BIOS-data to my lilo.conf (I ran lilo -v after the change) and the system still hangs. The Optiplex 320 is running bios 1.1.12
Why won't newer kernels work? Is there a way to get more information to print before the hang to aid in debugging?

Ive seen this a hundred times while searching google but I can't seem to get any of the fixes suggested to work for me.
Here are the specs code...
I have other servers on the same network with the same software/hardware that never loses its mount to the windows share, and nightly backups are run through those mounts. So why does the mount on this machine fail when we do a push? The only conclusion that I can come to is there is some sort of time out on the windows server that causes this. The other servers that have this same type mount use their share every night, where as the share on this server gets used once or twice a week. Once the mount hangs I can not unmount it, I have to reboot the server. Once the server is rebooted the push works fine. But then the next week when a push is tried it hangs. What else can I check?
UPDATE: I've also tried NFS mounts and autofs mounts and they hang as well
I enabled logging by echo 1 > cifsFYI and this is what I see in var/log/message code...
Ive removed the actual file names for security concerns. Any one have ideas as to why this is happening? The only other thing I can think of to try is to swap out the NIC but it's at a remote location so I can't do that right now.

I want to enable Firewire for my audio interface. I'm using ubuntu 10.10 (64 bit version).
lspci returns that I have a Texas instruments chipset. But when I search the kernal log file with grep, there are no references to this. I've searched for 1394, found nothing. I've read the whole thing and found references to Firewire_core, but looking online, this appears to be something else? I may be wrong, but my device is not recognised anywhere, as far as I can tell.
I have checked in Synaptic that I have the 1394 libraries installed, I do. And checked their dependencies are present.
I know that the device and the mobo are fine, as windows identifies the device with no trouble.
Can anyone tell me, what universe and multiverse means in relation to Synaptic packages, and how to enable these settings?
Also, should I expect my Firewire device to appear in the Places menu when it is recognised? It hasn't as yet, and I don't seem to be able to select for use as an audio interface in Ardour, the linux studio-recording program.
Maybe I've missed it completely, but I think the key problem is thers no reference to 1394 in my Kernel log.
lspci returns
03:0e.0 FireWire (IEEE 1394): Texas Instruments TSB43AB23 IEEE-1394a-2000 Controller (PHY/Link)
and the firewire_core stuff in the kernel.log

I would like to install Fedora 11 on an ASUS P5L-VM 1394 motherboard with a 3 GHz Pentium 4 CPU. This is an LGA775 socket mobo with a Intel 945G chipset. Two SATA hard drives are plugged into SATA ports. An IDE DVD drive is plugged into the IDE/ATA port. Using the 32 bit Fedora 11 installation disk, I have seen two cases:
1) No hard drive recognized. When i get to the disk configuration screen, there are no options to choose from.
2) By monkeying around with the BIOS settings or switching the SATA ports the disks are connected to, I can get an alternative mode in which no drivers are found for the DVD drive either.
Currently, a version of Ubuntu is installed. UPDATE: The board was purchased in a P3-PH4C barebones, which for unknown reasons requires a different BIOS issue than the regular P5L-VM 1394. Updating to the most recent BIOS does not resolve the problem. One the installation procedure fails to recognize the hard drives, going into a shell and examining the boot up log shows that the kernel recognized both hard drives. So it's down to why the installation procedure is not recognizing them.

I am having a bad slowdown issue when I enable Visual Effects with the Ati proprietary drivers that come with the installation. Everything runs very slow maximizing and minimizing take about 3-5 seconds per click and the effects get all choppy and don't look right like they did on my x1950 video card. I have tried downloading the current drivers from the ATI site but they don't seem to be initialising correctly after I perform the install.
I also know that the graphics card is not the culprit as it works perfectly fine on my Windows 7 64 bit install. There is no reason that my video card cannot handle the Visual Effects as it is a 1GB 4890 should have more than enough horsepower.
My machine is:
AMD Phenom II 965 Black Edition
8 GB G. Skill 1600 DDR3 Memory
1 TB Western Digital Caviar hard drive
1 GB 4890 Graphics Card ATI.

Anyone seeing a dramatic slowdown and "PAGE NOT FOUNDS" after the latest updates?
It even happens on LAN activity. Peak speed is excellent, the ability to resolve both local and WAN addresses is very spotty.
Machine is a newer Clone with AMD Phenom II dual core with 2gb running 10.04 32-bit with Gnome. Network is Gigabyte MoBo 1000-T ethernet hardwired to Dlink router into cablemodem.
XP and Win7 aren't affected.
It was ripping this morning, but right now, is pretty much crippled.

I have noticed that when iptables is active on my router i get a noticeable slowdown on browsing. This is untraceable through traceroute:
Code:
traceroute -n www.a-site-here.com
finishes immediately and at the same time when loading the site on firefox I am getting timeouts.
I use firewall builder to configure iptables. I have removed all rules while trying to find the one causing the problem, but even disabling all rules does not solve the problem. So, by leaving only an "accept-all" rule on firewall builder(so i don't lock myself outside) I still get slowdowns. In this case
Code:
iptables --list-rules
gives:
Code:
-P INPUT DROP
-P FORWARD DROP
-P OUTPUT DROP
