Randomnly when i try to hibernate or suspend the kernel hangs when trying to do that, this doesn't happened me before, with a old kernel it doesn't fail me 2.6.39,* i'm going to try the kernel version* without the RT.
Some times the KSOFTIRQ start to consume 100%(this is very strange because this happen very very randomly)
