General :: Grub (or Similar) Slow Down Boot Process?
Oct 30, 2010I wonder and hence ask you whether there is a difference in boot time between two systems when just one of them features grub at the boot stage.

General :: Slow Down The Kernel Boot Process?
Oct 14, 2010I'm trying to upgrad from kernel 2.6.32.9 to 2.6.34.3 and I'm having problems.The boot finished with that old gem "Kernel panic - not syncing: Attempting to kill init !"I suspect that it's something to do with my PATA IDE driver because there have been kernel changes in this area.My problem is all the boot messages scroll off the top of the screen before I can read them and it's no use saying look at dmesg or /var/log/messages because the root fs isn't there - another reason why I think it's to do with the drivers.So my question is, is there some way I can slow down the boot process so that I have a chance of reading the messages ?

Jan 6, 2010I have a Dell XPS M1330 with Opensuse 11.2 and Windows Vista Business in a dual boot hard disk.
I was using Fedora 11 before Opensuse, and it was fast and performed well. However I installed Opensuse because I like KDE 4.3 and this is the best KDE distro.
After the last kernel update my system lost initrd, I restored creating an initrd with chroot, mount and mkinitrd from a rescue disk. After first boot, I reinstalled the kernel update, so the initrd was replaced by the new one created in the update.
However, my system is very slow, I don't know where to look for bad configuration or anything else. The boot process took 220 seconds.
Here is my bootchar,

Feb 8, 2010I have OpenSUSE 11.2. I removed bootchart and forgot to run mkinitrd. Now, right at the start of the boot process, I get boot/93-bootchart.sh: line 17: 462 Terminated stopinitrd 5
I Can't find any 93-bootchart.sh anywhere. Earlier I got an error message about non existing /sbin/bootchartd, but I just copied /bin/cat to /sbin/bootchartd using a GParted boot disk. I tried to use chroot with an OpenSUSE boot disk, but mkinitrd can't find the root device, which is there actually (/dev/sda5). How can I make my system boot again? now I managed to re-install the bootchart rpm, using OpenSUSE boot disk and chmod. The system starts again. But that annoying bootchart is still there. I will not try again to remove it. First I will try to figure out, how to disable it during the boot process.
General :: Name Of Log File Where Boot Process Is Logged?
Apr 19, 2010I'm using CentOS 5.3. After booting up, where can I find the log file that contains if all services where successfully loaded or not? For example when computer boots you get a list of start services and they can be OK or FAILED. Is there a log file where this information is kept? I had a look in the following directory /var/log/ but not sure which one will contain the informaiton that I need.

Mar 15, 2011I've been reading various tutorials of the boot process but still am not clear. I don't care about grub stage 1 and 1.5 at the starting point of when the root filesystem is loaded into VFS(Virtualfilesystem), who is loading it, and from that point on. 1) Does grub load the root filesystem(read only) into VFS?2) Does the kernel load the root filesystem(read only) into VFS?3) Does INIT load the root filesystem(read only) into VFS?after this is concluded....Does INIT or the Kernel create the real root filesystem(rw)...right before the pivot.root

Feb 22, 2011I got home today to find that my KDE login screen would not let me log in. It said the authentication process failed or something and I needed to terminate the screen lock process manually. So I go over to another virtual terminal and try to log in. As soon as I enter my user name, a bunch of errors come up and I am unable to log in. "This can't be good" I think to myself, and reboot.
I am greeted by this error upon booting:
The error says that it says it cannot find /sbin/init. I loaded up a Ubuntu live CD and verified that /sbin/init is indeed present and all my other files still seem to be there. I tried booting into arch fallback on grub but that didn't work either. Midway through the day I SSHed my desktop from my phone and started it doing an upgrade. I was able to login.
General :: Process Control From Boot Loader To User Space
Jun 29, 2010For the past few days I was putting effort on understanding the software control flow starting from "Boot loader" to "Linux User space".
I am consolidating the entire process and putting forth in this forum...It would be great if someone can validate this..It might be useful to other new bees too.
Step 1 : Power up the board
Step 2 : The CPU control goes to EEPROM/storage memory where BIOS resides
Step 3: BIOS gets loaded in RAM and gets executed
Step 4: During execution, the selection of Boot device has to be done with the help of BIOS Menu [Blue screen appearance during start up in normal PC's]
Step 5: BIOS shall access the Bootloader stored in boot device [for eg.,Hard disk]. Boot loader is stored in MBR area.
for explanation purpose I take the following configurations
Bootloader = GRUB
Boot Device = Hard Disk
Step 6: GRUB shall be loaded in RAM and gets executed
Step 7: GRUB shall load the KERNEL image to RAM. Kernel image is stored in Hard Disk.
The question of "How the GRUB knows where the Kernel image is stored".
The answer is
1. In the "Grub.config" file, the location of "Kernel Image" and " Ramdisk Image" [which will be discussed later in the section] is being given.
Step 8: Kernel Image followed by Ramdisk Image is loaded in RAM by GRUB bootloader
Step 9: Kernel Image gets executed...During execution, top portion of the code shall make initial hardware initialization and latter part
of the code shall just decompress the Kernel Image
Step 10 : After decompressing the Kernel Image, it shall decompress
the already loaded Ramdisk Image
Ram disk is just creating a temporary hard disk in RAM. The main responsibility includes it consists of minimal driver files, executables, directory structures to created a TEMPORARY ROOT FILE SYSTEM.
This Temporary Root File system shall be used by Kernel Image
1. Execute the executables to access the Hard disk
2. For creating Permanent Root File System in HARD DISK
Step 11 : Kernel Shall look for the file /Linuxrc in Ramdisk. Linuxrc
is a USER script file [not sure]
Step 12: At the end of script file Linuxrc, the Ramdisk shall give the
control to "USER SPACE" [path for writing the script not known]in Linux kernel
Step 13: USER SPACE is the normal shell

View 6 Replies View RelatedGeneral :: Multi Boot Grub - All Systems Recognized But 10.10 Will Not Boot - Cannot Locate The UUID Specified
Dec 20, 2010Problem: I have installed two Ubuntu servers, 10.04 32-bit and 10.10 64-bit, in a multi-boot environment (also have FDOS and WinXPsp3). The 64-bit will not boot because grub can't find the UUID for the disk with the 64-bit system.
Brief Background: Installed 10.04 LTS two months ago with no problems. 10.04 is in a primary partition on hda with FDOS.
Installed 10.10 (64-bit) in a new primary partition on the same hd. The install seemed to go ok, but the MBR and the fs on the 10.04 were corrupted; could not boot. Restored drive, and rebuilt grub.
Installed 10.10 on separate hd (hdb). In grub step all OS's were recognized so I pointed the grub to hda. Grub failed to boot.
Rebuilt grub from 10.04 on hda. All systems recognized but 10.10 will not boot because it says it cannot locate the UUID specified.
Compared the grub.cfg for both systems, the UUID specified for hdb is the same. Also, when I mount the drive for 10.10 on the 10.04 system the drive UUID is consistent.
I know I must be missing some thing, but I know not what. Have searched and can't find any clues. All other OS's boot ok.
Hardware: AMD64 4GB, 2 internal IDE drives (hda and hdb), 1 internal SATA (hdc WinXP), various USB and Firewire Drives (no bootable systems).

Nov 29, 2010i am trying to change the boot order on the GRUB menu so that the countdown automatically starts on an older kernel. From what i can see all the solutions on the web want me to edit the /boot/grub/menu.lst file. The problem is that i don't have one. Someone also mentioned that if i don't have a menu.lst file then i should look for the grub.conf file. I don't have on of those either. The closest thing in /boot/grub is grub.cfg but that looks nothing like the descriptions i have heard of /boot/grub/menu.lst file

Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.
