Hi All,

I tried compiling linux kernel 2.6.37-rc2 (mainline), Compilation and installation of kernel and modules went fine. After that while trying to make initrd image, I used the following command :-

mohitdhingras@mohitdhingras-laptop:~$ sudo mkinitramfs -o initrd.img-2.6.37-rc2 2.6.37-rc2

It is showing warnings like :-
W: Possible missing firmware /lib/firmware/2.6.37-rc2/radeon/RV610_me.bin for module radeon
W: Possible missing firmware /lib/firmware/2.6.37-rc2/radeon/RV610_pfp.bin for module radeon
W: Possible missing firmware /lib/firmware/2.6.37-rc2/radeon/R600_me.bin for module radeon
W: Possible missing firmware /lib/firmware/2.6.37-rc2/radeon/R600_pfp.bin for module radeon

Actually, "2.6.37-rc2" folder is missing in "firmware".

Can somebody please help me out.

Thanks & Regards,
Mohit Dhingra

What distro do you have? And did you enable any firmware when you ran 'make xconfig'?

Hi Kenny Strawn,

Thanks for your reply. Here is some more information.

I have Ubuntu Distribution :-

mohitdhingras@mohitdhingras-laptop:~$ uname -a
Linux mohitdhingras-laptop 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux

I didn't enable any firmware, I ran make menuconfig & not make xconfig. I just enabled some debugging tools.

---------------
Other inputs from my side :

1. initrd image file is being made with few warnings as i mentioned earlier :-
W: Possible missing firmware /lib/firmware/2.6.37-rc2/radeon/RV610_me.bin for module radeon

But, the size of this image is 74.7 MB, while of my previous initrd image (2.6.31) was of only 7 MB.


2. vmcoreinfo file for 2.6.37 is missing. All of the files in my boot folder are as follows

mohitdhingras@mohitdhingras-laptop:/boot$ ls -al
total 96648
drwxr-xr-x 3 root root 4096 2010-11-22 00:12 .

3. Now, when i ran command "update-grub", initrd image gets added automatically. But, when i select this option (newly built) from bootup, the system gets freezed.

-----------------

Can you tell me , what did i miss, or what needs to be done to solve the problem.

Hi,

Now, I compiled .36 kernel version of mainline. It was showing the same warning messages while making initrd image, as I mentioned above. But I was able to run Linux in command line interface, in recovery mode. But when I select normal version, it comes till login screen and I am able to hear boot up sound, but then it shows garbled screen. I guess there is some problem with display driver only. My Display card is of ATI Radeon. And, it was showing the same related warning messages only while making initrd image.

Is it possible to use the same drivers, already available for kernel 2.6.31, in 2.6.36. If yes, how ? Or else what could be done?

It shows that ubuntu supports the driver you shouldn't have to compile a new 1. If you already added non-fre to repos, it should be available in synaptic, making it easier to install.

Yes, It was already installed in kernel 2.6.31. But I downloaded source code for kernel 2.6.36 and gave the build. After that , I updated grub and when I select the kernel 2.6.36 option, the display gets freezed. That is the problem. Now, when I have updated the kernel, I want same Ubuntu GUI Interface with this kernel. However, I am able to reach to Terminal directly via Recovery mode. And, it shows updated kernel version also.

Have you tried using the live-cd? For desktop version you just select try ubuntu, it puts you at a desktop that has a file that says examples, look under /usr/share/applications browse til you find icon for terminal.
