Date: Thu, 21 Feb 2013 13:26:54 +0800 From: Daniel J Blueman <daniel@...ascale-asia.com> To: Eilon Greenstein <eilong@...adcom.com>, Michael Chan <mchan@...adcom.com> CC: Steffen Persvold <sp@...ascale.com>, netdev@...r.kernel.org Subject: BCM5709 hang and state dump... Hi Michael/Eilon, On a large system with 552 cores, 1.5TB memory and linux 3.7, under some particular workloads, we've seem the Broadcom 5709 network controller hang [1]. It's running boot code 6.2.0 and NCSI code 2.0.11. We suspect completion timeouts may be occurring due to possible starvation. Is there anything significant/indicative from the state dumped? Many thanks, Daniel --- [1] bnx2: Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v2.2.3 (June 27, 2012) bnx2 0000:01:00.0 eth0: Broadcom NetXtreme II BCM5709 1000Base-T (C0) PCI Express found at
