Subject: PR/44734 CVS commit: src/sys/netatalk
Date: Sun, 8 May 2011 13:51:31 +0000

 Module Name:	src
 Committed By:	bouyer
 Date:		Sun May  8 13:51:31 UTC 2011

 Modified Files:
 	src/sys/netatalk: aarp.c aarp.h ddp_usrreq.c

 Log Message:
 aarpprobe() is called before MOWNER_ATTACH(&aarp_mowner), leading
 to a DIAGNOSTIC panic when MBUFTRACE is defined and atalkd is started.
 Fix by moving MOWNER_ATTACH(&aarp_mowner) to ddp_init().
 Should fix PR kern/44734
