----Next_Part(Tue_Jun_20_09_55_38_2006_364)-- Content-Type: Text/Plain; charset=us-ascii Content-Transfer-Encoding: 7bit Hi, all, When I testing -current, my pc panic at booting time. Message is 'lock "tcp_sc_head" XXXX already initialized'. So, I read @src/sys/netinet/tcp_syncache.c. It seems me that 'tcp_syncache.hashbase' should be zero cleared before calling, 289 mtx_init(&tcp_syncache.hashbase[i].sch_mtx, "tcp_sc_head 289 ", 290 NULL, MTX_DEF); Is it right? Thanks, ------- YAMAMOTO Shigeru <shigeru@iij.ad.jp> P.S. currently, I'm using following local patch. ----Next_Part(Tue_Jun_20_09_55_38_2006_364)-- Content-Type: Text/Plain; charset=us-ascii Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="tcp_syncache.c.diff" Index: sys/netinet/tcp_syncache.c =================================================================== RCS file: /share/cvsup/FreeBSD/current/usr/src/sys/netinet/tcp_syncache.c,v retrieving revision 1.92 diff -u -r1.92 tcp_syncache.c --- sys/netinet/tcp_syncache.c 18 Jun 2006 13:03:42 -0000 1.92 +++ sys/netinet/tcp_syncache.c 19 Jun 2006 03:01:00 -0000 @@ -281,7 +281,7 @@ /* Allocate the hash table. */ MALLOC(tcp_syncache.hashbase, struct syncache_head *, tcp_syncache.hashsize * sizeof(struct syncache_head), - M_SYNCACHE, M_WAITOK); + M_SYNCACHE, M_WAITOK | M_ZERO); /* Initialize the hash buckets. */ for (i = 0; i < tcp_syncache.hashsize; i++) { ----Next_Part(Tue_Jun_20_09_55_38_2006_364)----
