From d5a6be9e565c022a9b0d255e0e0e36149c77a272 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner <tglx@linutronix.de> Date: Tue, 14 Jul 2015 14:26:34 +0200 Subject: [PATCH 109/158] panic: skip get_random_bytes for RT_FULL in init_oops_id Disable on -RT. If this is invoked from irq-context we will have problems to acquire the sleeping lock.
