Hello,
Yes it does fix the issue.
Thanks a lot.
Shall I do anything to ask for this change to be included either in the
kernel or in the rt patch ?
Best regards
Christophe

Hello,
I'm trying to use the rt10 patch on a 3.4.2 kernel on a powerpc (MPC8xx)
system, and I'm having the following Oops during Irq initialisation. This
happens with CONFIG_PREEMPT_RT_FULL.
It doesn't happen with CONFIG_PREEMPT__LL
May someone help ?
Does the following uncompiled and untested patch fix it for you ?
Thanks,
