I installed the following packages:
ieee80211-kmdl-2.6.18-164.10.1.el5-1.2.18-22.el5.i686.rpm
ipw2200-kmdl-2.6.18-164.10.1.el5-1.2.0-45.2.0.1.el5.i686.rpm
from [URL] How to remove them completely? The ipw2200 driver complains that it could not agree with certain symbols in ieee80211 module. Before taking another route, I would like to know how to completely remove the files installed by these driver packages.
When I run yum list installed command the output shows two kernels:

Would it therefore be safe to remove the first kernel in the installed list to save having two kernels being updated everytime I run yum update? Or is the PAE kernel dependant upon the original?
I've searched high and low, and can't figure this one out. I have a older Olympus Camera (2001 or so). When I plug in the USB connection, I get the following log output:
$ dmesg | grep sd
[20047.625076] sd 21:0:0:0: Attached scsi generic sg7 type 0
[20047.627922] sd 21:0:0:0: [sdg] Attached SCSI removable disk
Secondly, the drive is not mounted in the FS, but when I run gphoto2 I get the following error:
$ gphoto2 --list-config
*** Error ***
An error occurred in the io-library ('Could not lock the device'): Camera is already in use.
*** Error (-60: 'Could not lock the device') ***
What command will unmount the drive. For example in Nautilus, I can right click and select "Safely Remove Device". After doing that, the /dev/sg7 and /dev/sdg devices are removed.
The output of gphoto2 is then:
# gphoto2 --list-config

/Camera Configuration/Picture Settings/shutter
/Camera Configuration/Picture Settings/aperture

Some things I've tried already are sdparm and sg3_utils, however I am unfamiliar with them, so it's possible I just didn't find the right command.
# mount | grep sdg
# mount | grep sg7
# umount /dev/sg7
umount: /dev/sg7: not mounted

Ok.. when it comes to drivers and kernels...I have a rented server - so I do not have local access to it, and I do not have a KVM or remote console to it.
This is the current kernel that came with it:
Linux version 2.6.26-2-686 (Debian 2.6.26-22lenny1) (dannf@debian.org) (gcc version 4.1.3 20080704 (prerelease) (Debian 4.1.2-25)) #1 SMP Wed May 12 21:56:10 UTC 2010 the network card module according to support is r8169 (when i do lsmod i see r8169 listed), lspci lists it as: Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03).
So.. where everything went bad is after I installed grsecurity kernel via apt-get install linux-image-grsec. It installed and rebooted successfully, but without the right network card module. The datacentre support had to reboot it to the original kernel for me.
So - i don't know how to update the network card drivers of the grsecurity kernel? It has to be perfect (I can't do trial and error) because each attempt that fails, I have to engage the datacentre support to reboot the system back into the original kernel. Apparently the new kernel detected it as a gigabit fibre card.
Running # lsmod | grep -e " 0 " | wc on one of my servers running CentOS 5.5 (64 bits) reports me 32 unused modules, I mean, modules with 0 references. Am I wrong interpreting these results? If I'm not, how can I automatically clean those unused modules (i.e not manually running modprobe -r ). Some years ago there used to be a daemon called kerneld who was in charge of that task, right? What's CentOS new equivalent?

I try to update my kernel to 2.6.18.128.4.1.el5 using

yum update installed:
CentOS (2.6.18-128.4.1.el5.centos.plusxen) and

both are not working. I have to run the system using: 2.6.18-128.1.14.el5. Upon trying again #yum update it says that no packages are marked for update. Can I manually install the desired kernel? Do you know a reason why yum update is not automatically installing the proper kernel?
I installed Centos 5.4 on my Pentium E5300 new comp, but I need IPX support in my work. It's simple - ipxutils and ncpfs from Fedora Core and new kernel with ipx support. I copied kernel config from /boot folder and activate ipx, ntfs support, and choose processor core 2 duo. New kernel (2.6.26) works OK, but I got one problem - when start it still shows message: "kernel: HUB 1.0:1.0 unable to enumerate USB device on port 1 (or 2, 3)" and stops after logging (text mode)
I got 2 USB devices connected - printer HP D5160 PhotoSmart and Scanner A3 USB Mustek, and I know scanner cause that messages but I don't understand why. Kernel config is the same like that from distro kernel (almost - ipx, ntfs and proc), but distro kernel doesn't do that. So I got 2 questions:
1. Why
2. What to do to stop that (disconnecting devices on boot time is not a solution)
So I have been trying to install these drivers forever and after going through a million forum posts and Google searches I have been unsuccessful. The process I have been trying starts as such: I hit ctrl-alt-f1 and then login as root. i then change to run level 3 by doing /sbin/init 3. After that's done I cd to desktop and do sh NVIDIA-LINUX-x86-185.18.29-pkg1.run --kernel-source-path /usr/src/kernel/2.6.18-128.2.1.el15-i686
If I don't give it the source path it can't find the source tree. Eventually I get the error: ERROR: Unable to load the kernel module 'nvidia.ko'. This happens most frequently when this kernel module was built against the wrong or improperly configured kernel sources, with a version of gcc that differs from the one used to build the target kernel, or if a driver such as rivafb/nvidiafb is present and prevents the NVIDIA kernel module from

I have been reading some books about device driver development etc.I made a char driver of bond (dummy) device. My book says that PCI devices contain three addressable regions,configuration space,IO ports,and device memory,the book talks about a file include/linux/pci_ids.h and PCI addressing etc.I read about following functions
1) pci_read_config_
2) pci_write_config_ some thing known as offset is defined to be passed on as an argument to above functions
3) IRQ number assigned to a card function pci_read_config_byte_,configuration register offsets
4) pci_request_region I want to write a pci driver for my own understanding and I am reading some books about it.

I am going to build a live-system out of it afterwards, and boot it from a USB. Don`t know if that has anything to say, but my experience has been that especially the /etc/network/interfaces keeps getting overwritten at boot-time as soon as I make it a live-system.
That`s why i was thinking of removing every network-driver upfront, such that Ubuntu has an empty database for network-cards.

View 1 Replies View RelatedUsing a Eee 900A netbook by Asus. By pressing Fn + F2, I can disable or enable the wireless chip on the netbook, a blue LED indicates the status. I've been able to connect to wireless networks just fine with this netbook. However, if the wireless chip ever becomes disabled, I have to reboot to get my network connection back. This generally happens when suspending. For some reason the LED will be off and I have to hit Fn + F2 for it to light up again.
However, after doing so, Linux will not reconnect to the network. It simply changes the wireless status from "wireless is disabled" to "device not ready". Even worse, I've recently had issues with the chip being enabled at boot, thus making it nearly impossible to get connected. I've searched around on-line but haven't found much of anything useful on this.

I have the latest ubuntu fully up-to-date.
I have started reading book Linux Device Drivers 3rd edition. So I want to know which is the best light weight distribution to use so that learning can be more generic and also does not involve distro specific nitty-gritty details. I have already tried building kernel for Ubuntu 10.04 but it involved different commands from what is mentioned in the book. So I am not sure whether I would be able to make further in the book. Has anybody tried?
