Help - Kernel panic

[Lebarhon]

Hello,

As planned I changed my mother board for an Intel DZ68DB. All the hardware seems fine, but I can't boot. After the Grub menu, I have an error message :
"Waiting for device sda6 to appear ( time out 1 mn)" sda6 being my / partition. and after:
"Waiting for device sda8 to appear (time out 1 mn)" sda8 being my /swap partition.
And some lines later, the Kernel Panic.

What can I do ? make a full reinstall ?
Thanks a lot for your precious advice.

good day

i have some baddish news.
expletives are allowed at this point.

if you haven´t already done so, do a reinstall but upgrade the mageia partition. the installer should ask. this should be the faster option.

if this doesn´t work, a new install. you will have to format the mageia partition and sacrifice any personal data so copy any such data off the drive first

have a pleasant hour or so.

I would try changing the sda6 partition in boot menu first. In both kernel and initrd line. It is possible that your new MB see hard drives letters differently (sdx).

For better diagnose of your problem it would help if you post content of file /boot/grub/menu.lst. Together with "sfdisk -l".

Full reinstall is wasting an opportunity to learn. Sometimes the solution in linux is literary changing one letter or number.

It is in mageia 1 errata that 1min timeout problem and you don't need to reinstall your mageia there is fix when you read errata page.
https://wiki.mageia.org/en/Mageia_1_Errata in down of that page there is guide to fix that problem.

Hello and thank you for the help,
But, to have a root access I need to connect with a live CD for example and it is worse than I feared because I haven't graphic displaying. As long it is in text mode, it is OK but soon after the grub menu, it is a black screen. I started in safe mode and I couldn't find any driver, neither Xorg Intel nor Xorg Vesa, any!
The driver suggested in Intel 810 and later.
I had a look in the BIOS, and selected several possibilities about the Integrated video in the processor, it didn't change anything.
I installed a second HD and make a new install, no change, no video.
There is many drivers and plenty of software in the CD shipped with the MB, for Windows only and I fear this MB can't work with Linux.
I could buy a new graphic card if I was sure it will work, what do you think ?

[benmc]

hello again

are you installing from a live cd or from mageia1 dvd?

if the later does the install get to a graphical configuration page for the keyboard, sound, network, etc?

if so, another if- are you able to test the graphics setting and save them here?

regards

I am installing from Mageia1 DVD. The installer made all its job with success as shown by the resume screen. In this page I tested the video configuration, the selected driver was i810 and later, the test didn't display the multicolor page but it didn't with the previous mother board either. I also tried Xorg Intel and Xorg Vesa with exactely the same problem.
There is no beep during the boot (no error to signal or beep don't work ?)
I wonder if it is a driver problem or if the MB is out of work and I have to use the guarantee?
Thanks again for your help

Things changed a little with the kernel option "nomodeset". Mageia started. I could then go in the MCC but no wifi and no Ethernet, so impossible to update. There was no driver that succeed the display test. I rebooted and now it is impossible to boot again with nomodeset or not. Same thing with a Live CD.
Now the boot stops at :
MTTR allocation failed
...
[drm] initialized i9115 1.6.0 ....

and after a while:
Login :

Maybe what filip suggests is the finest approach, but if you can't get into a shell neither chroot into your harddisks, you could try to check /boot/grub/menu.lst, /etc/fstab besides the BIOS recognition of your harddisks and their priority.

Now if you could post them here someone might be able to help

Hello,
You are right linuxero, it's because I tried to follow filip suggestion that I booted on a live CD and discovered that there was no display. The bios was OK.
So, I borrowed a graphic card (ATI HD4350) and now the display is working, I will open news threads if necessary for the other problems (so far, no Ethernet, Wi fi, printer, ..)
I would say to everybody to avoid Intel graphics HD 2000/3000, you have to be an expert to make it work.
IMHO, the mother board Intel DZ68DB isn't a good choice either because:
- no manual, a CD running under Windows only (may be its always the case now? Last year Asus MB were still shipped with a complete doc), no pdf for example accessible from Linux
- to use the documentation, you must have a second PC under windows or with the Internet
- ethernet problems, but it is also a flaw from Mageia, I often met it.
Now I have to give back the graphic card I borrowed and wait for the new one before I take over the wiki job I promised.
Thanks again for the ones who help me, it is good for the morale.

Sorry, but that opinion about Intel Sandybridge graphics is just plain wrong, or a settings problem on your end.
I've assembled like 200-300 machines last year, mostly all with only CPU-integrated graphics and Intel mainboards,
there was not one who wasn't working, except for some broken boards (yes, it happens from time to time, even with new boards)

Yes, there was never a printed manual, only a sticker with the pinouts and component locations on the board,
but IIRC the PDF was on the CD, which is the case for most mainboards these days. But mostly the manual
is not really needed for assembling, or settings, for the most part where it was needed were only some pinouts.
As it does not have BIOS settings explanations most of the time, it's not really helpful for something else.

For the ethernet problems, complain to the manufacturers, because they're the ones who use dirt-cheap GB-ethernet NICs.

Hello Doktor,
We aren't in the same world, I'm a simple Linux user, not an IT expert. When I said Intel graphics isn't working, it was implicitly with Mageia (I also tried Mandriva 2011, with no more success). I tried all possible drivers in Mageia and no one was working. Of course I found on the Intel website, sources and a dependencies list to compile the driver oneself, It was also possible to find information to write it, it is not an end user job.
I borrowed a HD 4350 and did it work fine in a few minutes, then I bought (this very afternoon) a Geforce GT520 and did it work in a few minutes, before that I had been wasting my time for full days and can't succeed to boot (except once). The obvious conclusion is that some graphics cards are easier to install than other and it is a good idea to avoid the difficulties. Heard the ones that have ears.
PS: I am angry against nobody.

Well, many people use Intel integrated graphics, my remark was just that i can't stand somebody giving an advice like:

I would say to everybody to avoid Intel graphics HD 2000/3000, you have to be an expert to make it work.

you should have worded it slightly otherwise, but as it stands, it is just wrong, and it's also a false advice,
which is a generalization based on one case of experience with that hardware. Do you see what i mean?

[linuxero]

Just regarding the latest Intel Integrated Graphics; I think there is something right to mentioning being a bit problematic. I would say it's the manufacturer fault to some extent because Intel explicitly states something about it's compatibility with the Processor used..!

A few months ago I had this friend with a brand-new Intel i7 and the IIG which exact model I can't remember. The IIG would NEVER work, not under windows, no nothing! The fault was simply that that same specific type wouldn't work with i7 processors and that's according to Intel.

Try using i5 or i3 processor and see if it works.

[doktor5000]

No need to try, you can use Intel's website for that, f.ex. for Lebarhons particular board: http://processormatch.intel.com/CompDB/ ... ame=DZ68DB
You can see that for some processors an standalone graphics card is required, but only for really few (4 out of 37 cpu series)
