Error while copiling the kernel

Hi...

i'm compiling the kernel using LTIB enviroment for iMX28 platform.

When the kernel is loading, it stops after the following serial print:

...

Looking other demo kernel, the following line should be:

audit: initializing netlink socket (disabled)

type=2000 audit(0.600:1): initialized

...any idea on wich packets include on the kernel configuration provided by LTIB?

Take a look at default governor in kernel settings :

CPU Power Management > Default CPUFreq Governor

use "performance" governor only.

The configuration was already in that mode.

Others ideas??

I had a similar lockup, the problem was the DDR frequency selected during CPU Freq. module init. Performance governor uses 200MHz which works always.

Anyway regarding your second question, if i understand correctly your asking for kernel source and config. If you selected "leave sources..." option in LTIB, kernel sources should be in /ltib/rpm/BUILD directory. Configs are in usual location in the kernel three.

Solve!!! Erase all. install ltib again and set FSL gnome release package
