Message-Id: <1186289484.636.5.camel@localhost.localdomain> Date: Sun, 05 Aug 2007 00:51:24 -0400 From: Steven Rostedt <rostedt@...dmis.org> To: "Paul E. McKenney" <paulmck@...ibm.com> Cc: Ingo Molnar <mingo@...e.hu>, Thomas Gleixner <tglx@...utronix.de>, RT <linux-rt-users@...r.kernel.org>, LKML <linux-kernel@...r.kernel.org> Subject: [BUG RT] - rcupreempt.c:133 on 2.6.23-rc1-rt7 Why is it, that every time I go to write examples for my chapter in a book, that I hit a bug! I got this on bootup of my Thinkpad G41 running SMP. Installing knfsd (copyright (C) 1996 okir@...ad.swb.de). WARNING: at kernel/rcupreempt.c:133 __rcu_read_lock() [<c010557a>] show_trace_log_lvl+0x35/0x54 [<c01061bd>] show_trace+0x2c/0x2e [<c01061e8>] dump_stack+0x29/0x2b [<c01660d9>] __rcu_read_lock+0x13f/0x14e [<c02f61fd>] ip_local_deliver+0x73/0x2b6 [<c02f5e74>] ip_rcv+0x2d8/0x5ee [<c02d4324>] netif_receive_skb+0x2b7/0x3fc [<c02d68b4>] process_backlog+0xb0/0x148 [<c02d6b6a>] net_rx_action+0xe0/0x1dd [<c01311a8>] ksoftirqd+0x126/0x240 [<c013f9d2>] kthread+0x44/0x69 [<c0105147>] kernel_thread_helper+0x7/0x10 ======================= I don't have time to look further now, and it's something that isn't easily reproducible (Well, it happened once out of two boots). If you need me to look further, or need a config or dmesg (I have both), then just give me a holler. -- Steve - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
