Date: Mon, 17 Oct 2011 18:35:37 +0200 From: Knut Petersen <Knut_Petersen@...nline.de> To: hpa@...or.com CC: linux-kernel@...r.kernel.org Subject: __cpuinit early_init_intel() called twice Well, I just realized that there are two "Disabled fast string operations" entries in the boot log - that means early_init_intel() is called _twice_. I had expected something else. Is this the expected behaviour or shall I have a look at the call trees? cu, Knut <6>[ 0.000000] Initializing cgroup subsys cpu <5>[ 0.000000] Linux version 3.0.6-main (knut@...em) (gcc version 4.5.1 20101208 [gcc-4_5-branch revision 167585] (SUSE Linux) ) #3 PREEMPT Tue Oct 4 13:58:23 CEST 2011 <6>[ 0.000000] Disabled fast string operations <6>[ 0.000000] BIOS-provided physical RAM map: <6>[ 0.000000] BIOS-e820: 0000000000000000 -
