Hardware :: CentOS DVD Hangs And Won't Boot From Usb Drive?

Sep 24, 2010

I am trying to boot the CentOS live cd off of usb. I used unetbootin to put CentOS on my 8gb usb drive after downloading the DVD iso. During boot it loads the image and continues until it reaches this point.

>Linux agpgart interface v0.101 (c) Dave Jones
>Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled

After this it hangs and won't continue. I am using a Compaq evo n800w and the bios is just updated to the latest version.

Ubuntu :: Hangs At Boot If USB Drive Not Attached

Jun 13, 2010

My computer is hanging on boot if I do not have the USB drive attached. The USB is in /etc/fstab as: UUID=023d6f83-04f5-4248-82d6-c2dbd1a77e18 /mnt/usbdrive ext4 defaults 0 0

This is all I can see on the monitor once it hangs (Ubuntu1004 is the label on my root filesystem): fsck from util-linux-ng 2.17.2 Ubuntu1004: clean, 56288/1921360 files, 425861/7681078 blocks

If I plug in the USB drive while it is at this point, it is happy and continues booting...

Here is some output from /var/log/messages if it helps at all (I'm assuming the 6.977 and 120.245 are times, meaning I plugged in the USB drive at 120 seconds, so you can see that it was hung up during that time):

Jun 13 11:35:30 BSERVER kernel: [ 6.791619] eth0: link up, 100Mbps, full-duplex, lpa 0xC5E1

Ubuntu :: Boot Hangs From Flash Drive On PC

Mar 28, 2011

I am trying to install Xubuntu from a flash drive on my PC. I used UNetBootin to get it on my flash drive. When it boots up I get to the Pre Splash screen and I choose Install Xubuntu, it goes to the Xubuntu Splash screen and just hangs there and hangs and hangs. Even if I click Try before Install, it just hangs.

I have a Pentium 4
20GB Hard Drive
512MB of Ram...

Is there a Text install? If so if I install that way will it install the desktop to or just command line? I figured maybe something went wrong when I put it on the flash drive so I am trying again.

CentOS 5 :: Hal Daemon Hangs On Boot?

Oct 27, 2010

I installed Centos 5.5 yesterday and discovered that the hal daemon was failing to start on boot.

The messages showed that the hal daemon was hanging because nss_ldap could not connect to the ldap server. It eventually failed and the system came up multiuser without it.

When I started looking into the problem I discovered that hald was being started quite early in the boot process. It's sequence number was 26 (if I remember correctly). This was even before nscd.

If I chkconfiged it off and booted, I could start it successfully once the system was up.

I changed the sequence number to 98 and bring it up relatively close to the end of the boot process.

This works and it starts normally.

Is starting it as early as 26 in the boot process done for a reason? It seems to me that it should definitely not be started before nscd. Does it matter that I moved it to the end of the boot process?

CentOS 5 :: Eth0/1/2 Device Hangs On Boot Up?

Apr 5, 2010

i have 5.4 installed on a super-micro server motherboard (has two gigabit ether ports). when i boot while its initializing everything it gets to the "starting eth0" and just stays there?

right before it boots up and says press any key for options i press a key and choose "centos (2.6.18-164.el5)" and it boots up fine but when i choose "centos (2,6,18-164.el5xen)" the problem occurs. and that is the default boot option.

CentOS 5 Hardware :: Boot Hangs With E1200 Processor?

Mar 28, 2009

System has a boot partition on raid1. The root filesystem is on RAID1/LVM.During the boot process, it gets to here:

Intel machine check architecture supported.
Intel machine check reporting enabled on CPU#1.
CPU1: Intel(R) Celeron(R) CPU E1200 @ 1.60GHz stepping 0d


most of the time, it will not reboot. I can cycle power, and, eventually, it does boot. So, hardware issue perhaps? Something else?What can I do, or add to the configuration to help debug this and figure out why? For boot options, I have tried noapic, apm=off, noht, nomce, nousb, nousbstorage, and none of those helped. As the machine is remote, to mess with console stuff, I have to get a KVM over IP hooked up, which I can do.

5 Hardware :: CentOS 5.4 Boot Hangs With CyberPower UPS / Solution For This?

Dec 13, 2009

Let me start off with the usual: I'm a linux newbie but am doing pretty good so far with google by my side. I've come across a problem I cant seem to find an answer to:

I just got a CyberPower 685 AVR UPS. I Installed their power panel software and it works great in CentOS 5.4. When I reboot, the system hangs right after the "Red Hat Nash 5.6..... Starting" message. I've left it for 20 mins so far and it's still hanging. If I unplug the USB data/shutdown cable, within about 10 seconds it starts detecting hard drives and continues booting...

Ive even returned the UPS for another to see if it was bad, and it still is giving me problems.

CentOS 5 :: Udev Hangs On Boot For A Long Time, Suspect Pam_console_apply?

Mar 24, 2010

I'm hoping someone knows about this one... I'm running the latest CentOS 5.4 with kernel 2.6.18-164.15.1.el5 (x86_64).When I boot the machine, it gets to the udev starting bit, hangs for like 5 minutes, then prints a message "Failed, will continue in the background." Then it boots OK after that.I tried booting again with the kernel option (from grub) "udevdebug", and what I saw when it tried again was a million messages saying it was waiting for "/sbin/pam_console_apply" to return, but I guess it wasn't returning... ;) Again, after 5 minutes, it gave up and finished booting.Now, this host is an LDAP client.

I figured that may have something to do with it as it is likely that pam_console_apply tries to make an LDAP lookup, which is wrong, because networking hasn't even started yet. If I disable LDAP (by removing ldap lookups in nsswitch.conf), I get no pam_console_apply errors from udev and it boots quickly. But that's a bummer, I need LDAP on this box, and I don't want my boot time to be 7-8 minutes. ;)Presumably before, when LDAP was enabled and it waited 5 minutes and then notified me that it will "continue in the background", that it was eventually successful after networking started. LDAP otherwise works fine on this box, just like all the other servers we have.This is new behavior, I've not seen it with CentOS 5.3 and below. Has anyone seen this? Any hints on what I can do to avoid it? It seems like a pam bug or something, but I don't know for sure.

CentOS 5 :: Grub Doesn't Automatically Boot OS After Install, Hangs At Grub Prompt?

Mar 21, 2011

I have used CentOS for a while and have never run into this issue. I searched all over and didn't see a similar issue anywhere, I did an install of CentOS as a server (no GUI) with only the base. Partition is /boot ext3, size of 100MB. The rest of the drive is partitioned as / with ext3. This is being done on a CompactFlash card of 32GB in size. The BIOS sees it as an IDE drive.

When the install completes and the system reboots, the grub stops at the grub> prompt. There is no menu for OS options. If I do the following commands:
grub>root (hd0,0)
grub>kernel /vmlinuz-2.6.18-194.el5 root=LABEL=/
grub>initrd /initrd-2.6.18-194.el5.img

CentOS 5 :: Installed 5.3 On An External USB Drive But Can't Boot From It

Oct 5, 2009

I recently installed CentOS 5.3 (from DVD media) on a Seagate 320GB external USB drive; this drive is connected to an Intel-based desktop computer (Intel D945GNT motherboard) with two internal SATA drives (both NTFS, as I'm running Windows XP SP3 as my primary OS). The install found the USB drive fine, and I manually configured my partitions; I had the install place the boot loader in the first sector of the boot partition of the external USB drive. I had set my BIOS to boot from the USB drive first; after a reboot, nothing happened...no GRUB menu, nada.

After some research, I had found an article discussing the need to rebuild the initrd for USB drive support. So, I booted the computer from the CentOS DVD, then went into 'linux rescue' mode; once I was at a command prompt, I navigated to the /boot directory and executed the following command:

mkinitrd --with-usb --preload=ehci-hcd --preload=usb-storage --preload=scsi_mod --preload=sd_mod ./usbinitrd-2.6.18-128.el5 2.6.18-128.el5

After the new "usbinitrd" was created, I edited grub.conf to reflect the new image, then attempted the reboot again from the USB drive. Still no GRUB menu.

CentOS 5 Hardware :: Can't Boot With External USB Drive Installed?

Sep 30, 2009

I installed the latest download of centos 5 on to a older dell optiplex gx260. install went fine. I then hooked up an external 1tb USB drive, formatted it ext3 from inside the LVM, and mounted it to /usb-mnt. the mount command is in /etc/fstab like normal: /dev/1tb-usb/1tb-usb /usb-mnt ext3 defaults 1 2

all of the steps taken were straight out of the gui now on boot up I get: checking filesystems fsck.ext3" No such file or directory while trying to open /dev/1tb-usb/1tb-usb [FAILED]

*** an error occurred during the file system check
*** Droping you to a shell; the system will reboot
*** when you leave the shell.
give root password for maintenance
(or type control-D to continue):

and yeah all the /dev entries are gone. I have rebooted in linux rescue mode from the install cd, commented out fstab and been able to boot. but that doesn't actually get me to having this disk available. how to I get the system to see the drive again? if I add it back to fstab is just goes into the above. I don't seem to be able to get LVM to see the disk anymore to reformat it, I can't get the system to allow me to access it so I seem stuck.

so how do you get the system to reprobe and add a drive that once existed? uname -a output: Linux guff.domain.edu 2.6.18-128.el5 #1 SMP Wed Jan 21 10:44:23 EST 2009 i686 i686 i386 GNU/Linux

CentOS 5 :: A Twist On The Boot Installation USB Flash Drive?

Sep 23, 2010

A Twist on the Boot Installation USB Flash Drive Have made numerous attempts at making a bootable installation USB Flash drive for CentOS 5.5 but in one way or another they all came up short.Using dd to apply bootdisk.img to a flash drive per the installation instructions seems to take over the entire device even though it only needs about 10 megabytes.Using the method outlined in the Wiki article Set Up a USB Key to Install CentOS and other similar methods causes vmlinuz and initrd to load very slowly. About 50 seconds compared to normal of less than 10 seconds. The dots going across the screen is like watching paint dry.Data partition not accessible to Windows machines.

The following adaptation of the Wiki content article Set Up a USB Key to Install CentOS by Phil Schaffner overcomes the aforementioned short falls. Much thanks to those who created the original content sources and processes. None of the following is originally mine. I just altered it a bit to overcome the aforementioned short falls.

Overview: Objective of the following procedure is to create a CentOS bootable flash disk also containing install iso and kickstart file, that does not suffer from the aforementioned short falls. Partition 1 Installation iso, kickstart file and anything else such as post install scripts, etc. Partition 2 Boot Partition ~15 megabytes.

/dev/hda = IDE/ATA
dev/sda - /dev/sdf = SATA
/dev/sda - /dev/sdd = RAID5 for storage

CentOS 5 :: Dual Boot With Windows RAID And Drive Combination

Jan 8, 2011

I have a pre-existing setup with Windows XP Professional and CentOS5.5 on a dual boot setup with the Linux drive setup as the primary drive hosting the grub menu.

I am replacing these machines with new updated ones and they have windows setup on a RAID0. I think it would be easiest to follow my previous setup and move the RAID to secondary SATA ports and put the linux drive on the primary SATA port, or should I just change the boot order in the BIOS to have the secondary linux drive boot first?

can I move a RAID setup to secondary controller ports without breaking the RAID?

CentOS 5 :: Udev Hangs After Upgrade To CentOS 5.4?

May 7, 2010

I have encountered the same problem as indicated in this post: "udev hang after upgrade from 5.3 to 5.4"[URL]... I'm testing the upgrade path to centos 5.4 on several virtual machines prior to upgrading our production systems. I have upgraded centos 5.2 --> centos 5.4 and centos 5.3 to centos 5.4. In both cases udev hangs after the upgrade. The following message is displayed on the console: "Starting udev: Wait timeout. Will continue in the background [FAILED]"

I found another related post: "udev hangs on boot for a long time, suspect pam_console_apply"[URL]..So, I booted by VMs using the "udevdebug" option to grub and received the same error message - "udevd-event [###]: run_program: Waiting ## seconds for output of '/sbin/pam_console_apply /dev/..."

In my /etc/ldap.conf file "bind_policy hard" is commented out. I added a line "bind_policy soft" as described in the post and my VMs booted fine. NOTE: This problem is not encountered with a fresh install of CentOS 5.4 and the "bind_policy hard" option in the /etc/ldap.conf is commented out as in the upgraded systems. What is really causing this problem and how do I get it addressed? I have a couple hundred systems to update from various releases of CentOS 5 to the latest current version 5.4. It would be nice to get this bug squashed..

OpenSUSE Hardware :: GRUB To Dual Boot 11.2 And Windows XP But Hangs On Boot

Apr 20, 2010

HW config is: AMD Athlon 64 X2 5000+ Black Edition, MSI 785GTM-E45, 2X 1Gb Kingston HyperX PC2-8500. I have set up GRUB to dualboot openSUSE 11.2 and WindowsXP. Initially i had set up system with defaults: CPU@2600MHz (200X13) and therefore RAM@800MHz. Both openSUSE 11.2 and WindowsXP worked just fine. Memtest86 found no problems.

But after a while i decided to change this setup to: CPU@2500MHz (250X10) and therefore RAM@1000MHz, as it promised better overall performance. And now Windows still boots and works better then before. Memtest86 still can't find any problem. But openSUSE 11.2 hangs at boot. I've suspected cpufreq governor, but changing from Ondemand to Conservative in /sys/devices/system/cpu/cpu0/cpufreq doesn't help.

Ubuntu :: Boot Hangs (sometimes) After Dual Boot Screen?

May 25, 2010

I'm running Ubuntu 10.04 and a small Windows 7 partition (cuz I can't get Ubuntu to run my MSI TV@nywhere plus card but that's another issue).I can log into Windows fine. If I choose Ubuntu, however, the boot process will go thru a few screen flickers. Then one of two things happens:1) I get a scrambled up pixelated image (not sure what it is) for about 3 second, then it goes into the login screen and I can log in normally.2) I get the scrambled up pixelated image and it hangs. This happens about 4 times out of 5 when rebooting.

I do have an nVidia card and a beta driver (they published it the 21st, I believe, of this month) but this happened long before that. It's happened ever since I installed any of the drivers (I've tried a couple different versions, hoping to fix this) for my card.

My system is a frankenputer:
Phenom II quad core 3.0 cpu
nVidia GeForce BFG 6600
500G drive

Note: I do have 3D rendering when I finally get into the desktop. Everything works great, except that when I'm playing my mmorpg, Regnum Online, it freezes the entire computer and I have to reboot (not sure if that has anything to do with it or not).In case it's needed, this is my grub:(Second note: I'm sorry for the length of the post but I don't know how to upload documents/files to show)

# from /etc/grub.d and settings from /etc/default/grub

Hardware :: External USB Drive - Mkfs Hangs / Solution For This?

Nov 13, 2010

I have a 1TB external USB drive that I'm having a lot of trouble with.

First I created a 500G partition, then formatted it with ext3. That went as expected.

Then I tried to copy a large (~50G) archive to it, and at about 13G it just stopped. I was using "watch" to view the progress, and it just stopped suddenly. I left it for quite a while, to see if it was actually doing something, just slowly, but nothing.

I tried to kill the copy command, but it wouldn't die. I killed the parent processes, and it just kept moving up the process tree until init was its parent. I tried rebooting.. I got the message "system is going down for reboot now", then the first few messages of the reboot process, and then it just stopped at "unmounting local filesystems". Again, I left it for a while, nothing. I ended up hard booting it.

After rebooting, I recreated the partition, then tried formatting it. This time it started writing inode tables, then just stopped at a certain point. I think at 133/4001. Again, I left it for a while and it didn't move.

Again, I tried killing the process and it moved up the tree until init was its parent. Rebooting hung at the same place, and again had to hard boot it.

This time I deleted the partition and tried creating a small partition - 500M. mkfs formatted it as expected, and I was able to mount and write to the partition.

I deleted the small partition, and tried creating a larger one - 100G this time. fdisk created the partition just fine (and did not complain or report any errors through this whole process), but again mkfs gets stuck.. this time at 34/801 inode tables. I haven't been timing it, but I want to say it's been at least 10 - 15 minutes.

dmesg reports some drive errors, but I'm not sure what they mean code...

Software :: System Hangs - Possible Drive Failure - When Try To Watch Videos ?

Jul 10, 2010

Lately (in the past couple of weeks) my system has been hanging, particularly when I try to watch videos. I'm not sure why this is happening, but when I looked through my system log files I found what's on the attached file. A couple of other programs that I use frequently (xmms2d and epiphany) have similar entries, and I assumed they are related because they are typically running when the slowdowns occur. Also, my /home partition is giving some errors which may or may not be related.
