Hi guys!

I've been Linux user for more than 10 years, I've installed Linux tens (or maybe even more) times and never had a problem which I couldn't get by...

But now, I'm stuck with Gentoo on Dell PE 6850. It's my first time with Gentoo - all the time until now I was orthodox Slackware user, but it seems to be dying, so I decided to move to some more recent distro (and with better support).

I've tried to install Gentoo (64-bit version) several times. Installation goes OK, but first reboot after installation is complete gives me kernel panic (uanble to mount root ...).
I thought that I'm doing some mistakes with kernel configuration, so I tried those options:
- manual kernel configuration (via menuconfig)
- using kernel from install CD (as described at https://wiki.gentoo.org/wiki/Gentoo_installation_tips_and_tricks#Using_the_Installation_CD_kernel)
- using genkernel
- using 'make allyesconfig'
- extracting config.gz from CD-booted Gentoo and using it for fresh compillation
- using 'huge' kernel from Slackware.

Only last option (using Slackware kernel) gave some result - kernel was able to find and mount hdd's, but during booting some errors came out, and finally login prompt appeared, but I wasn't able to login - keyboard (and whole PC) was not responding (even NumLock/CapsLock LED's were dead).

I thought, maybe this server is in some way 'non-compatible' with Linux and it needs some piece od magic to make it work ;) So (to check it) I put Slackware 14.1 DVD (it's version from 2013 - so much older than newest Gentoo which I was trying to install), chose 'full install' and after 15mins I had fully working and booting correctly OS.

Probably I'm making some stupid mistake... but I have no clue, what could it be. It's my first time with Gentoo... and I don't want to leave it this way and switch to another distro.
I've searched Gentoo forum, but all threads that could be related to my problem were really old (from 2002-2006) - so I don't think, that they could help me in any way.

Boot-CD detects HDD's without any problem (it's RAID1), server has PERC 4e/Di RAID controller.

Please...help. I'm really stuck :(

You need to get your kernel configuration right and Gentoo will boot up. There are many threads here about the very error you are getting, so I'm not going to repeat everything here.
Is this PERC 4e/Di RAID fakeraid?

Hi,

boot with a working install cd and run "lspci -k". It should show you the used driver for your perc raid controller and you can select the correct one in your kernel config afterwards.

Maybe you can add the output here or via wgetpaste and we can try to select the driver together.

greets, bb

Thanks for your suggestions.

But - if it was a problem with kernel configuration, some missing drivers and/or modules, one of things that I've tried before posting to Gentto forum was 'make allyesconfig' - which 'Generates a new kernel configuration with all options set to yes.'.

So (as I understand description above) option 'allyesconfig' includes EVERYTHING into kernel - also EVERY possible driver. And kernel configured this way (I assume, that it had all drivers included) must have had support for my RAID device. And, as I wrote in my first post - 'allyesconfig' kernel also didn't work. So I'm afraid, that problem might be somewhere else.

Of course I can paste here my lspci (a little bit later), but please explain me - if you are right and there some missing drivers, so what does 'allyesconfig' do and why didn't it work for me?

@Buffoon - actually I don't know how to tell fakeraid from 'real' one, but because this is a real rack server, HDD's are SCSI not IDE/SATA, PERC has it's own GUI and a lot of possibilities of configuration, it has it's battery and RAM - I assume, that this is real hardware RAID, not fake.

lubandzia,

That view of allyessconfig is a bit simplistic. Over the years, drivers have been rewritten. In some cases allyesconfig will turn on two or more drivers for the same hardware, which is a very bad thing, as neither will work.

The liveCD kernel is made with genkernel all. If that worked, you can do that too.

For further help, post the output ot lspci -k,
df -T, with your filesystems mounted and the exact text of the panic message. The unknown-block(x,y) is especially useful as x any y tell what the kernel failed on.

Thanks - I'll try once again with genkernel, but with 'all' option.

And if this helps - I will then create my own, customized kernel, dedicated to my PowerEdge server.

I thought, that using 'allyesconfig' makes me 100% (or even more ;)) sure, that everything needed is included in kernel, so when it failed, I was sure that problem is somewhere else, apart from kernel configuration. But maybe you guys are right.. I'll do genkernel once again and I will see what happens then ;)
