The patch titled Subject: Revert "lib/test_printf.c: call wait_for_random_bytes() before plain %p tests" has been removed from the -mm tree. Its filename was revert-lib-test_printfc-call-wait_for_random_bytes-before-plain-%p-tests.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Petr Mladek <pmladek@xxxxxxxx> Subject: Revert "lib/test_printf.c: call wait_for_random_bytes() before plain %p tests" Revert ee410f15b1418f2f442 ("lib/test_printf.c: call wait_for_random_bytes() before plain %p tests"). It might prevent the machine from booting. It would wait for enough randomness at the very beginning of kernel_init(). But there is basically nothing running in parallel that would help to produce any randomness.
