From 1817dc0370873caff77b924b53ae489edaf9b1e2 Mon Sep 17 00:00:00 2001 From: "Voss, Nikolaus" Date: Tue, 25 Jan 2011 15:07:29 -0800 Subject: [PATCH] drivers/clocksource/tcb_clksrc.c: fix init sequence setup_irq() was called before clockevents_register_device() which is needed by the irq handler. Bug was reproducible by restarting the kernel using kexec (reliable crash).
