General :: Invalid ACPI: Invalid PBLK Length [5] During Debian Boot
Sep 20, 2010I installed Debian 5.03 Lenny successfully on my machine. I got this error during boot: ACPI : invalid PBLK length [5]. After that the Operating System boots properly and starts normally. What does this error statement mean? Is it safe to work with this installation despite this error?
View 1 Replies View RelatedGeneral :: Necessary To Set Boot Flag?
Jan 24, 2011In another forum (I each day visit a lot of them) a user was stating that you need to set a boot flag to make the root partition bootable, if you create partitions with GParted in order to install a Linux with GRUB2. Another was suggesting that, if you install Linux with GRUB2, the installer automatically sets a boot flag to the root partition to make it bootable (I don't remember the names). I neither believe the first nor the second thesis and I'm hoping that in this excellent forum some Gurus not only are saying I'm right but also give a comprehensive answer.

Aug 25, 2010When I boot, after startup and before I log on, an error icon appears. I click - it shows a summary of the material that normally rolls by on a unix startup. One item is checked. It says:
Code:
Enabling /etc/fstab swaps: swapon: /dev/mapping/vg_knox-lv_swap:
read swap header failed: invalid argument
I have 1 disk - it has 2 partitions - one an 83 type with a file system in it, holds the kernel, mounts at /boot.
The second partition is an 8e type contains a volume group logically split between lv_root and lv_swap and physically located on sda2. As I understand it, the system is having trouble processing the commands for lv_swap. I am tempted to mess with these commands, but don't have enough know how to do so and am short on the time required to learn enough to master this subject.

View 1 Replies View RelatedUbuntu Installation :: Separate Boot Partition - Doesn't Care About The Boot Flag On The Disk
Feb 14, 2010GNU GRUB 0.97
Ubuntu 8.04.4
2.6.24-26
Added an SSD (dev/sdc) and decided to move some less often changed directories there. Started with /usr and /boot, leaving / on a primary in the first drive, for now. All started ok, and my changed fstab mounted the right ones, and the system works.
However, grub is actually using the original /boot on / on sda1. I cannot see any way to change this. (Which makes it sorta hard to update the kernel
From grub:
Okay, since it has two choices, I tried to tell it which one to use. But, grub> root (hd2,5) does nothing.
Disk /dev/sda:
what I seem to recall, grub doesn't care about the boot flag on the disk. Nor does it care about primary vs. logical (except GNU doc says "makeactive" only works on a primary?).
The GNU doc also indicates that it looks for a directory /boot on the partition, so if you're mounting a partition as /boot, it also needs to contain a /boot directory under it. Tried that, but no change.
Is my problem the logical partition? Does that prevent "grub> root" from changing it? I'm afraid to wipe out the old /boot and find that I can't start up.
Programming :: Cannot Understand Invalid Read Error
Aug 25, 2010I have just started using Valgrind,which really is great. Most of the reported errors look kinda weird, though I can't really understand what's going on here, for example:
==00:00:02:52.033 7754== Invalid read of size 4
==00:00:02:52.033 7754== at 0x80B0987: MyCls::MyPrintf(long, char*, ...) (MyCls.cpp:270) ...

270 cout<<endl<<"m_FilePtr="<<hex<<m_FilePtr<<dec<<endl;
Basically, Valgrind reported the "Invalid Read" error at line 270 of file MyCls.cpp, which is simply a cout of the m_FilePtr variable, which is a member variable of the MyCls class. It's a FILE* variable I use to write repeatedly on a text file. The address reported (0x47a5ee8) is 296 bytes after the "this" pointer (0x47a5dc0),as Valgrind correctly tells me but I honestly don't understand that. And of course, I need to read that variable, not only for the cout (indeed,the error is reported at every reading attempt). Besides, the application doesn't crash, but still I would like to understand if I really have to worry about this "error".
Ubuntu :: Can't Boot Except With Noacpi Flag

Ubuntu :: Win7 - Changed Partition Flag To Boot
Jun 2, 2011I just installed windows 7 and ubuntu stopped booting even though it was still there, so I thought I would just change the partition flag to boot. I found out later that I had to create a new mbr but after I changed the boot flag, windows 7 stopped booting and I tried changing it back, but it didnt work. So I was wondering if i didn't use the correct flags or is there another way to get windows 7 to boot again? I was using GParted to change the partition flags and that i am using windows 7 ultimate 64bit

Feb 10, 2011Trying simply to insert into table. Have succeeded in doing this but now want to correct user use of invalid characters. If I'm understanding correctly, Real-escape-string seems to correct these, so I've been trying to figure out how to use it. A short, test code version gives me a syntax error at INSERT VALUES, which--because it still has the single quotes in the text--tells me the real-escape-string didn't work. The code below gives me a parseing error with invalid $END at </body>.

OpenSUSE Install :: GRUB Chainloading Removed Boot-flag
Dec 13, 2009I had my BIOS complaing that there were no OS. (worked since releaseday of 11.2).
partition setup:
sda1 : primary : swap
sda2 : primary : ext3 : Kubuntu
sda3 : primary : ext3 : opensuse (flagged as bootable)
sda5 : logical
sda6 : logical
opensuses GRUB is primary and Kubuntus is chainloaded.
The problem occurred after I tried to boot kubuntu for the first time since I installed opensuse. Kubuntu didn't boot. so I probably set up chainloading wrong. No big deal, this I can fix.
The big problem was that after trying to boot Kubuntu no OS was marked as "Boot" in MBR. This is VERY strange. somehow the boot-flag is removed!
After setting the boot-flag (with a live-CD) everything works again. I can reproduce this.
I've tried to find answers but could'nt find any.
Is GRUB supposed to remove the boot-flag when chainloading? have I found a bug?

Sep 7, 2010I'm trying to mount my new Western Digital Elements 2tb hard drive, but every time I try to plug it into the computer I get this error message:
Quote:
Error mounting: mount exited with exit code 12: Failed to read last sector (3907027119): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS),
[code].....
But when I tried opening the hard drive from nautilus I still got the same error message as above (no other volumes was connected at the time). I've also tried opening and watching it in GParted, and I can see it there as a volume that's not allocated. When I tried to allocate the hard it I got the message that it had no partition table. And that I cold make one. I tried and Ubuntu suggested to make a MS-DOS partition table for it. But there I got a little scared as I've not done this before. The external hard drive is brand new and was brought today. And I don't have the possibility to test it with Windows or Mac as I'm using Linux only on my machines.
Fedora Installation :: Boot Any Current Kernel Without The Nolapic Flag On ICH8-based Intel T7300 Systems?
Jun 16, 2009Is there a way to boot any current kernel without the nolapic flag on ICH8-based intel T7300 systems? This system works fine with the last 2.26 kernel from FC8, but due to EOL of the security updates I tried to install FC11 and FC10. The first sign of trouble is that their installation only works with acpi=off or nolapic options. As those options disable either fan-control or the second cpu-core I consider them undesirable. Is there a recent correctly working kernel available? Or do I have to downgrade to a distribution that uses a 2.26 kernel?

Ubuntu :: Laptop Boot Failure - Invalid Enviroment Block - Unable To Load Default Boot Entries

General :: Boot Up Process- The Read Only Rootfs Into VFS?

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

View 3 Replies View RelatedGeneral :: Root File System Is Mounted Read-only On Boot On Gentoo?
Sep 27, 2010I am using Gentoo Linux and for a while now, the root file system is mounted read-only on booting. For obvious reasons, this is quite annoying as most services do not start up correctly (I do not use a separate file system for /var). After the system is up, I have to log in, remount the root file system read-write, fix /etc/mtab, mount all other file systems in from /etc/fstab and then start up all the missing daemons. I know that there are ways to make a system run properly with a read-only file system, but I would rather restore the old behaviour of a writable root file system.
The strange thing is that after running mount / -o remount,rw, the file system is mounted in writable mode without any errors. I suspected some problem with fsck, but now I have disabled automatic file system checks on the partition (tune2fs -c0 -i0).When I run dmesg, only these lines mention the partition at all, although I am not sure if not something gets lost because /var/log is not writable:
EXT3-fs (sda5): mounted filesystem with writeback data mode</code>
EXT3-fs (sda5): using internal journal
The line in /etc/fstab looks like this:

CentOS 5 :: CMOS Password Reset Possible From Within It?
Oct 7, 2010I have a lost password on an Intel DG33TL motherboard which I guess is only resetable by shorting the right jumpers on the board. I have two questions regarding that:
1- Is there any way I can reset the CMOS password through the CentOS? Or is that a thing of old motherboards where one could reset them through the OS?
2- Currently I have two hard drives installed in Raid1 (mirroring each other) through the motherboard RAID (not the through any RAID card or through CentOS). RAID was made prior to installing CentOS. So, would resetting the jumper mess up the whole RAID? I don't want trouble and I can leave without the password but it's good to know if need arises.
