You're not giving enough information. Which Buildroot version are you using ? Which kernel version ? Which kernel configuration ? You need to post the complete boot log of your system. Also, this is very likely not a Buildroot issue, but a kernel configuration issue. But if you don't provide more details, we really can't help.
Not enough information, after 3 months. Closing.
