Hi all, I compiled the current upstream Linux kernel with "make allyesconfig". The boot messages are full of the following lines: random: get_random_u32 called from allocate_slab with crng_init=0 random: get_random_u32 called from allocate_slab with crng_init=0 random: get_random_u32 called from allocate_slab with crng_init=0 ...... random: get_random_u32 called from allocate_slab with crng_init=0 It seems CONFIG_PRINTK_INDEX can help reduce such boot messages. But the message still occurs. Anyone knows which kernel config actually controls the appearance of messages? Thanks in advance. -- My best regards to you. No System Is Safe!
