I installed Debian Lenny on my HP Laptop - dv6-2120ed. Because i have atheros wireless card i needed to install ath9k which is not supported in 2.6.26 kernel so i compiled it to 2.6.32. Everything is good, but when i boot the new kernel i get "Bar 6: No parent found of for device" for 2 devices - the ethernet LAN card and the sound card. After 1 minute waiting the kernel starts booting and everything works fine (the LAN and the SOUND card too). How can i fix this and what means it exactly?

Hello,
this error spams about 100 times, then the scanner does indeed work. So I'm not completely broken, but the error messages are of concern, and it slows down the process of scanning for the time it takes to do the messages.

Since installing F11, my Canon LIDE 50 scanner refuses to work. xsane 0.996 produces an error message: Failed to start scanner: Error during device I/O.
sane-find-scanner says it is there: found USB scanner (vendor=0x04a9 [Canon], product=0x2213 [CanoScan], chip=GL841?) at libusb:001:006 But scanimage -L claims: No scanners were identified.except once when it admitted: device `genesys:libusb:001:006' is a Canon LiDE 35/40/50 flatbed scanner
I reluctantly tested the scanner on a Windoze machine and it works perfectly. And it worked perfectly under F10.

I installed debian 4.0 (etch) on an old computer with some pickled graphics card in it, and then I upgraded the computer to one with slightly newer hardware only without the graphics card (the new one used on board graphics). I moved the hard drive from the old one to the new one but when I booted it up it failed to start the X-server and I got some errors listed for "device not found" and "no screens found".
I tried using "dpkg-reconfigure xserver-xorg" however I can't seem to find a working configuration. It seems pretty silly that when installing debian it can detect all this automatically with no problems but when it comes to changing some hardware around you are left in the dark with a complicated re-configuration process. Is there not some way to automate this? I'd rather not have to re-install everything

I've been testing Squeeze to determine whether KDE4 is finally suitable for my primary machine. Everything seems to be working fine except for detection of IDE devices. My CD/DVD drive no longer automounts and the reason seems to be that no device is being created. My Lenny system detects the drive as /dev/hda, but no such device exists in Squeeze. During boot, Squeeze appears to detect the drive as /dev/sr0 (according to dmesg), but in fact that device does not exist either.I'm actually running the Lenny kernel, as I am unable to compile my Ralink wireless driver (rt2860sta) using the Squeeze kernel. Also, for inquiring minds, I use removable HDD drive bays on my systems to simplify testing.
View 9 Replies View RelatedThe computer networking works fine with a normal static setup, but adding a USB wireless device is not successful. It is my own network so the wpa-ssid and wpa-psk are known to work with Lenny and a previous wireless device.The device is recognized (lsusb) and the driver is confirmed to be in the kernel (lsmod). Here is the iwconfig output:

After typing: ifconfig wlan0 192.168.1.144 up I can ping that address, but it is not working. I have just done a fresh install of Sid so that I could get the 2.6.35 kernel which contains the ath9k_htc driver for the USB wireless device that I am using. The firmware is ar9271.fw but my source of that is questionable because it does not seem readily available. I am temporarily using a PCMCIA wired connection which is what I am using to connect to the computer via telnet. (This is just for convenience so as to avoid getting up all the time.) Here is the ifconfig output:

That file works with the previous USB wireless device under Lenny. Am I doing something wrong or is the driver and firmware just not up to snuff yet?

I have been following the Xen Beginners Guide here: [URL] .....
Everything was going smoothly until I got to the 'Configuring xen-tools and building our guest' section (two thirds down the page).
I installed xen-tools and then typed the following in a terminal window (as root):
xen-create-image --hostname=development-pv-guest --memory=2048mb --vcpus=2 --lvm=develop --dhcp --pygrub --dist=jessie
I admit PV is new to me, compared to simple HVM, so I have a number of questions:
1. Why the command not found error?
2. Should I be booting from the Xen option or regular boot option at the start up screen when creating the xen image? I've tried both and get the same error message.
3. I have Debian 8 (Jessie) installed on my system and I wasn't sure whether I should therefore make this the guest OS in my Xen PV. In asking this question I'm thinking in terms of HVMs - but I assume my Xen PV needs a guest OS of some kind? Or is my host Debian 8 already acting as a guest OS in Xen PV? I'm confused
4. If I do need to install a guest OS, is it better to go for an earlier version of debian - so as not to be so resource hungry?
I'm nervous about screwing up my host debian installation, so when I got the error message, did some research but found nothing meaningful. I don't want to end up having to reinstall my Debian 8 (base OS) ... again!
I installed ndiswrapper and tried adding a driver. Error: module ndiswrapper not found.So I recompiled my kernel, upgrading to 2.6.33.4 (no, I can't see the logical connection either) After a week, I got the new kernel working ( in the interim I reinstalled debian- it didn't survive my first kernel attempt. don't ask), and reinstalled ndiswrapper. Same problem. So I had a stoke of genius: download the source package!! So I did. Lo and behold, a new directory appeared in /usr/src/ : modules. I took a moment to admire my work, then I jumped in.I 'ls'ed to see what was going on, and found a Makefile. so I typed 'make'. First error: kernel source not found. So I entered the Makefile, found the(clearly marked)variable,and changed it to /usr/src/linux-2.6.33.4 , exited, and redid 'make' Second error: no wireless support in kernel. So I went to src/linux-2.6.33.4 and did a make menuconfig- loaded my current, threw in wireless, and exited.

Anywho, I reinstalled debian from the kde CD on the debian website, it auto-configured my network out of the box. My network is connected to the computer, pinging google works perfectly, and ifconfig shows that eth0 is working correctly without any errors. However on both Konqueror and Iceweasel, every time I try to connect to a website, it tells me the server cannot be found. Basically it acts like I don't have internet. Using the terminal works though, I have installed KDE-FULL from the terminal and wicd, so I know I do have internet. I don't know what it could be, like I said, I installed from the cd and this happened. Maybe there's a bug on the KDE debian cd

I'm not sure if this is a bug in Squeeze beta 2 or if it's something I've overlooked. I have a Maxtor 250 GB external USB drive that I use for backups. It gets auto-mounted fine, always in the same place, and from my normal user account I can write to it, even delete directories on it if I want to. But when, from Gnome, I select the "Safely remove" option, I get an error to the effect that it can't stop the device. The weird thing is that the thing actually *is* unmounted. I've checked the mount point and it's no longer there.Is there some package I maybe should've installed but haven't? I'm not really worried about data loss, since I'm sure the drive wouldn't unmount unless it was properly synched; it's just the error message that bugs me.
