Moving from 2.4 to 2.6 guide

Ok, still trying 2.6.0-test1 :oops:

And I'm having a little problem. The bootup works fine, and I'm amased by the fact that 2.6 reads my battery state by default with ACPI on

ooohhhh HAPPY DAYS

The problem is X. It wont start. I can't find why. I have a Radeon. Everything worked just fine with 2.4 so what might I be doing wrong?
I had DRI enabled in kernel and tried to shut it of, with the same result. Any good ideas guys?

Any hints on how stuff works (or not) with the nForce2 (nforce-net) motherboards?

Officially, nVidia is not yet supporting the 2.6.0 (nor the 2.5.x) kernel tree, but will release drivers as soon as 2.6.0 goes out of beta.

Anyone any luck with these?

Although "test2" appears to have numerous usb updates applied
to it, I still can't get my usb mouse to work. It's a MS optical wheel
mouse that works perfectly under the 2.4 series. Is everyone still
having the mouse problems? I've tried compiling everything into
the kernel as well as everything as modules. Also my intel
card is no longer working (under 2.6) the e100 driver doesn't
seem to work. Again, this work flawlessly under 2.4. Any insight
would be appreciated.

I have Hardware Promise Raid, and i have set the promise 76 module compiled in.
It doesn't work.

I have also been looking for the other software raid etc options that was mensioned in the qoutes in the first post. But i just couldn't find it. Don't know why.

The options were:
support for IDE RAID controllers
and Support Promise software RAID (Fasttrak(tm)

Has anyone got this to work?

I'm using test3 by the way.

It's not a XFree86 problem. The Optical light doesn't turn on when the kernel boots.

can I use nvidia drivers in both 2.4 and 2.6 ? When I am trying to switch between 2.4 and 2.6, nvidia module compiled with one does not load with the other? is there a way to have two instances and switch between them as needed ?

I'd really like to see how kernel 2.6 runs on my old PII 300, so I'm trying it out, but from 2.6.0-test1 to 2.6.0-test3 I'm seeing the same problem at boot:

Cannot mount or read hda6 or "hda6"
Please append a correct "root=" option to your grub config
Kernel Panic (blah blah blah)

Now, I've been fiddling with 2.4 series kernels for a while, and I've
always been able to get them to boot using grub. My 2.6 config is
almost identical to my 2.4 config in /boot/grub/grub.conf

############## begin grub.conf ##############
default 0
timeout 10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=Gentoo Linux 1.4 (2.4.21)
root (hd0,0)
kernel=(hd0,0)/boot/bzImage.2.4.21 root=/dev/hda6 ro hdc=ide-scsi

title=Gentoo Linux 1.4 (2.6.0-test3)
root (hd0,0)
kernel=(hd0,0)/boot/bzImage-2.6.0-test3 root=/dev/hda6 ro hdc=ide-scsi

############## end grub.conf #############

Below is my fstab setup
################### begin fstab ####################
# <fs> <mountpoint> <type> <opts> <dump/pass>
/dev/hda1 /boot reiserfs noauto,noatime,notail 1 2
/dev/hda6 / reiserfs noatime 0 1
/dev/hda5 none swap sw 0 0
/dev/fd0 /mnt/floppy auto defaults,user,noauto 0 0
/dev/cdrom /mnt/cdrom iso9660 defaults,user,noauto,ro 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
################### end fstab ####################

I have Reiserfs enabled in my kernel config, I'm telling /dev to mount
at boot. The 2.4.21 kernel configured above boots every time like a champ,
but the 2.6 kernel always gives me a kernel panic when it tries to mount
/dev/hda6 to /.

Any ideas? Your help would be greatly appreciated. Thanks.

tried 2.6 in my box and .. not impressed.

The first thing that I noticed was mouse freezes once in a while, as if getting stuck in mud while moving across the screen :evil:

then, it didn't really feel fast. 2.4 after gentoo patch is better.

or may be I could not perceive the difference because my system IS good.

So .. why bother. I am not moving onto it, until gentoo-source embraces it.

The only benefit that I saw was high memory support worked the first time I tried it. But, gentoo-sources-r6 apparently has fixed it, and it works without a glitch.

And am I missing something, or ReiseFS4 didn't get included in 2.6?

I just got 2.6.0-test3 operating ok. I had issues with nvidia-kernel until someone said I had to use `ACCEPTED_KEYWORDS="~i386" emerge nvidia-kernel nvidia-glx` and then it went fine. My sound still doesn't work, but that's not a huge deal for me.

What is weird though, is when I go into X+fluxbox, Eterm, aterm, and xterm all crash and close immediately when loading them. I haven't played enough or looked for anything in my error logs, but they did (and still) work fine in 2.4.20-gentoo-r2 and 2.4.20-gentoo-r6.

I, as someone noted, had to create /sys (I got a message in my boot script stating /sys was not created, and to create it.) Once I did, my SCSI controller (a Compaq SMART2-SL) only showed the partitions there, not in /dev, so I had to modify /etc/fstab so my /home direcotyr mounted properly in 2.6. This had to be changed back (along with the linux symlink) when booting back to 2.4 (as should be expected.)

I also did what someone suggested elsewhere, create a linux-stable to go with the linux-beta, and symlinked 'linux' to these symlinks. I also, as noted in this post, renamed all my bzImages to append the kernel ebuild that was used.

When I ran make && make modules_install with /boot mounted, it moved vmlinuz and config to the boot partition on its own, but I use bzImage, so I removed them and unmounted boot next time I compiled the 2.6 kernel.

Last thing I can think of right now, is I created a 'video' directory in /usr/src/ and copied & renamed nvidia.o from my various kernels so everytime I recompile one, I can recopy them if re-emerging nvidia-kernel removed them (which it did for me).

I ran test1 for some weeks, without ANY issues - really, NOTHING went wrong. It's amazing how stable this "beta" is, I wish every final would be that great

So if you think about trying it, go ahead. It's not hard, and will work almost for sure - oh, did I mention I ran the beta on a laptop? Without any issues? I guess I said so

Having alsa in the kernel really makes life easier, not to mention the better ACPI support, often had issues with the 2.4 in that field (toshiba really bitches around with that stuff :wink:

).

Compiling test3 ATM, hopefully that runs just as smooth as test1 did.

To those having problems with IntelliMouse Opticals on USB:

Did you enable USB support, and USB HID support? HIDBP mouse might not make a difference (but it's said to be a sort of hack)...

Finally, did you enable Input core support as well as the input support for keyboards, mice, etc.?

I haven't tried the development-sources so they might have changed, but this is what I would suggest for, say, a 2.4 kernel.

I am having the same issues with the USB m$ mouse.. I am using hotplug to autoload modules, but i will try to load modules manually, see what happens...

allex87 · Posted: Sat Aug 23, 2003 2:32 pm Post subject:

OK, I solved the problem!!! run from a console

modprobe hid

To load it automatically:

Create a file: /etc/modules.autoload.d/kernel-2.6. In that file, simply put all the modules you would like to load automatically. Simply put the text hid there!

I am now experiencing problems with my sound card...I get errors that say: Unable to open audio device '/dev/mixer'.

Anyone knows what the problem is now?

Thanks,
Alex.

Hi I tried to download the latest development sources as instructed above, however every time I try I keep getting kicked out of all of the portage servers and I just get a message saying modules-init-tools 0.9.12.tar.bz2.... Connection times out', or 'no path to file' or '404 file not found', what's going on? Where have the modules-init-tools got to? I can use emerge for just about anything else.

Q

Wow! Just moved to 2.6.0-beta4-mm1 (mm-sources). All I have to say that it simply works! It's great! It's fast! Outstanding! Not having a single problem!

Build kernel.
Reboot.
Works...

Hmm, with vailla test4 my system keeps haning on the hotplug part. But that could have something to do with the nForce2-ishness of the mobo (however, no external net, sound or agp stuff has been emerged for it by me)

ftp://www.kernel.org/pub/linux/kernel/people/rusty/modules/module-init-tools-0.9.13-pre2.tar.bz2 works for me.
