My computer acts strange - sometimes reboots spontanousely, sometimes does not want to boot. When I isse command "mcelog", I receive such info:
[Code]..
How can I read and understand it? Could somebody point me to some documentation?
First off let me say thanks psy_unix and fuji, the pci=nomsi allowed me actually finish install on my laptop. (Read this post)
Problems do not stop here however...Now, when it reboots after install all I get is a "Machine Check Exception" followed by a "Kernel Panic". I had to switch back to Vista Home finally (not happy about that).
I just bought it and it runs happily under Vista, I just don't run happily under Vista.
How to get CentOS running on this one?
Information:
Laptop:
Compaq CQ60-206US
CPU: AMD Athlon X2 64 bit (2Ghz Dual Core)
Mem: 2 GB
OS: CentOS 5.3 (tried 32 and 64 bit)
I have also tried CentOS 5.2 (32 and 64 bit) with the same results.
I 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

MyCls::MyPrintf (this=0x47a5dc0, iPrm=3,
sMsg=0x6974320 "blablabla"...) at 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".
write a script that will check all filesystems to see if they are read-only.
I have come up with ...
df -h > /tmp/mount.lst
awk '{print $6}' /tmp/mount.lst > /tmp/mounted_systems.lst
This gives me ..
Mounted
/
/boot
/dev/shm
/proc
So now I have ..
How do I automatically get rid of the 'Mounted' header in my /tmp/mounted_systems.lst file ?
Also, I don't want to check the /proc filesystem, so how do I remove that within the script too.
Then I will run ...
while read dir
do
touch $dir/read_only_test
done < /tmp/mounted_systems.lst
If the filesystem is read only, I want that filesystem name to be listed into another file.
I face "read error " while booting. sometimes it start normally. someone told me to check hard disk for errors. i used gsmartcontrol for this. but from its result i am unable to decide is this hard disk failure or just minor errors. can somebody tell me do i require to change my hd or it just something else to cause such error.

View 2 Replies View RelatedIn the beginning there is MBR. MBR looks for the active partition and tranfers control to the VBR of the active partition. MBR is where grub may be installed. which allows the user to choose an OS(a VBR) I am not sure what the program in the VBR does,but it manages to loads the OS. What am I trying to do: Backup. I ma tired of losign my partitions my bootloaders. I want to backup them all! partitions/MBR /VBR everything short of creating an disk image.
My questions:
1. say the ubuntu partition is formatted, will grub still load? if not is there a bootloader that would?am I making sense? i hope so...
2. what exactly does the VBR contain ?
2. How do I go about backing up? The mbr and the partiton table are backed up with a simple dd command. Then what else needs to be backed ? VBR's of every partition?

I need a script that dose the following checks if files exists by read input from a file then compares them to the files listed in the directory if they don’t exists the script would report back which file dose not exists. I also need to format the output so that files are grouped in different groups, group A, B, and C and etc based on file name. I would like the output of that do not exists files to be sorted based on second number in the file name than group according. I understand some of the basics of bash scripting something along of the lines of a loop and if statements might do the trick. Below is what I have so far. I don’t car so much about the script reporting back the file exists I prefer to only know if the file is missing and is less than 3 days old. Problem is if a file dose not exists in the reports file the test compares against the wrong file.

Previously I'd been using the open source CUPS driver, which seemed to work pretty well. However, I recently ran low on one colour of toner which messed up the printing. The toner-out lights on the printer never cam one, so replacing the toner cartridge was not the first thing I tried to fix it.
I've just installed the hplip / hp-plugin driver which also seems to be working. However, the CUPS web interface doesn't allow me to retrieve the toner status.
Has anyone had any luck retrieving the toner levels from an HP colour laserjet printer?
I used k3b to write a music CD on my Asus laptop. I then put it back in the drive, and Kubuntu told me that it was blank. Yet when I brought it over to a different machine, or to a non-computer CD player, it played correctly. The files on the CD are WAV, not MP3.
I've heard of problems where you write a CD in one machine and then can't read it in a different machine, but this is the other way around! The originating machine can't read it but the foreign machines can. I don't understand that at all.
The default writing speed is 24X. I tried lowering it to 16X, but that had no effect.

I have some file tools on a mint machine that I would rather not install on my mac laptop. Mainly because of the vastness of apt-get and the low risk of installation failure. Anyway, every so often I have a file that I want to process in place using some remote tool. Both machines can ssh right in to each other so I was figuring there must be some script or tool out there that would allow me to type out something like remote [file] [tool & args] to send my file to the other machine, get it processed, then get it back.
