Greetings from Poland
 
Hi everyone,
I'm Marcin and I'm working on my masters degree currently. It's based on a ARM platform working with a linux OS onboard. I have some troubles with that that's why I am posting here.

The ARM platform is Versatile Express with Cortex-A9 onboard. I made it work together with linux 3.2 ipipe-kernel but i had to start over and ... an error poped out that have nerver appeared before. This is what's able to be seen on console:

Code:

## Booting kernel from Legacy Image at 00008000 ...
  Image Name:  linux-3.2
  Image Type:  ARM Linux Kernel Image (uncompressed)
  Data Size:    5900684 Bytes =  5.6 MB
  Load Address: 60008000
  Entry Point:  60008000
  Loading Kernel Image ... OK
OK

...(and so on)

I have no clue what might be the problem (the "Initializing cgroup subsys cpuset" fraze is displaying over and over again to infinity)

I'd be glad if anybody have any solutions.

regards,
Marcin Kuska

http://www.kernel.org/doc/Documentat...ps/cgroups.txt has some clues that may suggest your disto is trying to associate kernel to some group and it failing.


Arm or whoever built it should have better information. The vendors tend to have some sdk or tools to help or at least some known working version to start you off.

The solution was to extract fresh linux kernel (make mrproper did not work) and apply every patch you need from the begining. I have no idea what was the problem but this worked.
