I recently installed debian squeeze 32bit on a second partition of my amd athlon 64 X2 dual core machine.Currently it is using linux-image-2.6.32-trunk-686 kernel.But linux-image-2.6.32-trunk-amd64 is available.on the repository.Is it a 64bit kernel or 32bit kernel optimized for amd64 architecture?

I've been following grub-common bug #606845 and in coming to a solution for the issue, these guys are using dd as a brute force means of swapping out master boot records or trampling them, if you prefer. (Background: The issue is related to grub and certain xp installations)
An sample snip of code:
dd if=/mbrxp.bin of=/dev/sda bs=512 count=1
1) Is mbrxp.bin a back-up of the mbr taken before installation of squeeze (or grub in general)?
2) Am I fubar if I didn't make a back-up of the mbr before installing grub?

default in openSUSE 11.2 we have installed kernel-desktop. This kernel is optimized for the desktop.
What is the name of kernel optimized for server machine? In my case Firebird database + Apache + PHP?

I have a problem with my custom kernel when I want to create the Nvidia kernel module.After this finished I installed the image and headers and created the Nvidia kernel module. Everything worked fine.However, if I remove the linux-source from my home directory then I can't create the kernel module.Even though I have the headers for the kernel installed.

I have a set of vm's with stable, testing, and sid to keep track of how things are going. When I did an apt-get dist-upgrade with squeeze last week, things seemed to OK (350 package updates) until the end. It didn't seem to like and / or was confused by a kernel dependency.
I am not too concerned yet. Because these are in vm's, I do a snapshot before any significant change. I can futz around with impunity because I have that backup.
I re-booted, and tried the apt-get dist-upgrade again with same results. I think I also tried apt-get -f install.
So I reverted to the snapshot, and will simply try again in the future. I recall that with lenny as testing, the font-desktop was really screwed up for about a period of 6 weeks.
However, just in case someone else runs into this:
1) a re-boot worked, but the failure of apt-get made me nervous enough to revert.
2) waiting for corrections has seemed to work in the past (with a single exception with a 4-disk SCSI software RAID10 update that failed to re-boot lenny successfully after what seemed to be a minor update -- that was on a real system, not a vm. I haven't gotten back to look at that.)

I have two servers (A and B) which are identical. My idea was to have a software RAID 1 with both of them running and if server A craps out I wanted to swap the hard drives from server B into server A. When I tried to test this idea the network driver doesn't seem to want to cooperate. ifconfig gives nothing and I can't figure out why. From googling I've read that a network card has a unique ID on it (I'm assuming their talking about the MAC address) and is used in some config files which is why swapping hard drives gives two different MAC addresses and confuses the system. If that is so would anyone know exactly what config files the mac address is stored/used in? That way I can make a backup of those files and swap those out if I ever need to swap out the hard drives.

For a good while I used the following code to swap caps lock and escape, which is very beneficial to me as I have vim-like keybindings in most of the apps that I use:remove Lock = Caps_Lock
add Lock = Escape
keysym Caps_Lock = Escape
keysym Escape = Caps_Lock
followed by xmodmap ~/.Xmodmap, which I got from http://vim.wikia.com
/wiki/Map_caps_lock_to_escape_in_XWindows. However, after a recent Debian upgrade with aptitude, this stopped working - or, it does work poorly, in that caps lock toggles caps lock and acts as escape, so I have to press it twice all the time. Is there a better way to do this with X, since my solution stopped working?

On Lenny, due to some compatibility issues: kernels before 2.6.26 don't recognize part of my vaio laptop's hardware, while the last drivers of my videocard (version: 260, card: nvidia gt 230m) suffer some incompatibility problem (this is one of the most problematic computers I ever had), so I have to use version 256, which doesn't work with kernels after (perhaps) 2.6.32. So, I suppose I have to check each kernel between that two versions and hope that one of them will be ok. I searched quite deeply over the net but didn't find anything related to debian, except for generic kernels [URL], but as someone told me that it's better if I only install stuff from the stable repository or backports. What can I do? Is there any backports archive or something like that? Otherwise, what should I do?

I recently bought an AMD R7 360 videocard and I'd like to use the free Radeon driver.
Problem is, PCI-ID 0x665f is not present in Jessie's 3.16 kernel sources. The hardware however is supported, it's just not recognized. So I'll have to get the Debain sources and patch include/drm/drm_pciids.h
From the 4.1rc1 kernel I know what to patch and where.
Debian page that explains how to use the Debian build system for recompiling the current kernel from Debian packages?

Upgraded Wheezy to Jessie, by changing my apt sources to point at stable instead of wheezy. Ran upgrade, and dist-upgrade, all fine etc.
Then tried to update the kernel by installing linux-image-amd64 package .. seemed to work fine, but after a reboot my kernel version still says 3.10.23
What have I missed?
Code: Select allroot@hostname:~# apt-cache search linux-image
linux-headers-3.16.0-4-amd64 - Header files for Linux 3.16.0-4-amd64
linux-image-3.16.0-4-amd64 - Linux 3.16 for 64-bit PCs
linux-image-3.16.0-4-amd64-dbg - Debugging symbols for Linux 3.16.0-4-amd64

I have a MyBookLive where i installed a Debian 2.6 kernel. The system is running fine so far. Because of an error message when apt-get upgrade (udev) i tried to upgrade to 3.16. Here's what i did:
- apt-get install linux-image-xx
- apt-get install linux-source-xx
- extract the source
- copied the old .config from running 2.6 kernel over to the 3.16 directory
- make oldconfig
- make uImage
- make modules
- make modules_install
- copied uImage to /boot
No error messages because its a headless device - its just not booting up.

I was wondering if anyone can assist me. I am looking to build a server with Debian as the host. When I installed Debian (Squeeze) the default kernel was "2.6.32-3-trunk-amd64". When I tried to install 'Virtualbox' application, I got a failure because I didn't have the 'kernel-headers' installed on my machine. I noticed there are no specific header package the 'trunk' kernel I was using. I have a few questions so I guess I should begin:
Is it safe to remove the 'trunk' kernel and boot my system on just the regular 2.6.32-3-amd64 kernel? Is this OK or not recommended? Please explain whatever is the correct answer. This is my 1st time using a 'Trunk' kernel so I don't know the in's and out's of it.
If I am using Debian 'Testing' for virtualization via 'Vbox', is there a specific kernel I "should" be using?

My girlfriend got a 'new' (second hand) laptop, a HP Compaq 6715s. When I tried to install Debian on it, the install went immensely slow - glacial, even. It was a very minimal install but it tooks hours to get to nowhere.
I found out online that this was because of a problem between the current kernel and the hard drive (or HD bus, something hardware-y to do with the disk) which meant file operations were extremely slow. I thought "easy, patiently install Debian and then install newer kernel". Except that after six hours, the install wasn't even halfway.
So I install Arch Linux with the 2.6.35 kernel: no problems with the drive speed at all. After a lot of researching (I only played around with Arch once, more than a year ago) I got the system into a usable state. But now wlan0 has suddenly disappeared, together with some other problems - and a usable laptop wasn't exactly what I had in mind, it was supposed to be awesome (or at least good). Which, with Debian, it would be
So... is it possible to make a Debian installation use a later version of a kernel? I'd want to install Debian with the 2.6.35 kernel, not install Debian and then afterwards update the kernel (because I don't have 24 hours to install an OS, if it'll ever even install).
I've found some stuff online but it might well have been written in the Cyrillic alphabet. All I understand, I think, is that in theory it's possible.

I installed Debian Squeeze from a net install to a raid 1 array. I have been having a lot of troubles related to being able to write to one or more of the mounted drives - even touch gives me errors.
The most interesting line from dmesg is:
Here is the full output from dmesg:
I found a thread that indicated that this bug was fixed in the next kernel version: 2.6.32-6. I am willing to upgrade the kernel to get rid of my problems. Is a squeeze kernel at 2.6.32-6 or higher available? If so, where? I have not compiled my own kernel, and am not very interested in getting into that.

Trying to compile the 2.6.36.2 kernel. Its not the first kernel I've compiled, but I've run into a problem I've not come accross before.
While compiling I get this error.
[Code]....
Looks like the headers sys/eventfd.h and linux/virtio_rng.h haven't been selected in my .config file. I just copied my old config from the last kernel I built. This was a while ago (2.6.30), but I thought I'd give it a go anyway.
what config option they are under or what I can do to get rid of this error?

This is Wheezy x86_64. I tried two different ways to install kernel 2.6.38 on my machine and both have failed. First thing I did was to follow this guide [URL]... el-26.html) and try to compile the latest stable from kernel.org. I don't know why, but it turns into kernel panic when I try to run it. Second thing I did was to install the liquorix 2.6.38, and that also fails, seeming to boot but hanging a second short from the login. I don't know what I'm doing wrong. Is there a special way to install kernels in Debian? This is the first time I tried compiling a kernel, so it's quite likely that the problem is sitting 6 inches from the computer screen. Also, how would I remove those kernels since they're obviously not working? I know I could remove them from the grub menu but I'm not sure how to completely delete them.

This morning I upgraded two of my systems. The new 2.6.38 kernel fixed the missing pointer on the system that has an Intel video subsystem. Yay!
This afternoon I tried to upgrade my wife's systems. Aptitude is listing 2.6.32 as obsolete, but it isn't offering me 2.6.38. Was it withdrawn?

I'm running testing, so yesterday I upgraded to the new kernel (2.6.38). Unluckly I can't get to the desktop, because the system just hangs (screen goes black then nothing happens). I have found that my problem is the radeon (open-source) driver. When the it tries to get to the desktop it enters an infinite loop, so the system hangs. The bug is better described here: [URL]. However, I don't know how to fix it. I would prefer not to go to the fglrx (proprietary) driver because of tearing issues.

From the securing-debian-howto [URL] ...
"4.2.2 Security update of the kernel
First, make sure your kernel is being managed through the packaging system."
which suggests...
Code: Select all$ dpkg -S ‘readlink -f /vmlinuz‘
When I try to confirm by running the above, I get a lot of characters of output but the last line reads...
Code: Select alldpkg-query: no path found matching pattern /vmlinuz‘
How do I make sure my kernel is being managed through a packaging system?

kernel with which most version number may be compiled in Debian 5 stable without updating to testing? 2.6.32.8 can't compile, if not turn off virtualization, since Documentation/least/least.c
contains
#include <sys/eventfd.h>
which is present in libc6-dev from testing, but is absent in stable.To drivers compiling kernel used own linux/eventfd.h.
