Hi @Markus, thanks for the response. I'm making headway into the android/ power.c problem. As far as I cant tell the correct approach is to patch the 2.6.24 kernel specifically the files:
lib/kobject.c include/linux/kobject.h To have the functions: kobject_init_ng, kobject_add_ng, and kobject_init_and_add [details from http://linux.derkeiler.com/Mailing-Lists/Kernel/2007-12/msg00659.html] I'm having trouble at the moment as I can't seem to apply the patch file. I'm having to make the changes by hand. If you have any pointers / comments please let me know. @ Deepak - Out of interest, what development board are you using? I'm using the freescale I.MX31 ADS Kind Regards, Ben On Sep 23, 11:34 am, Markus <[EMAIL PROTECTED]> wrote: > Hi > > @Ben: On the first sight, your patch looks fine.
