The problem happens when XGene SlimPRO Mailbox (CONFIG_XGENE_SLIMPRO_MBOX) is loaded after XGene I2C SlimPRO (CONFIG_I2C_XGENE_SLIMPRO).
To fix this issue, please help change CONFIG_XGENE_SLIMPRO_MBOX to builtin, not module.

It might be worth trying to make the modules depend on each other. So add something like this to the /etc/modprobe.d/modulename.conf file:

softdep pre:<module-which-must-load-first> <module-which-is-second>
