Message-ID: <50CDC4F0.6010206@wpkg.org> Date: Sun, 16 Dec 2012 14:56:16 +0200 From: Tomasz Chmielewski <mangoo@...g.org> To: linux-kernel@...r.kernel.org, netdev@...r.kernel.org Subject: BUG: unable to handle kernel NULL pointer dereference + panic on 3.2.11 (with various networking pointers, on Dell r720xd) Hi, a server running 3.2.11 just crashed with rather lengthy (~3 MB) dump: http://www.virtall.com/files/temp/3.2.11-panic.txt Any pointers, info if it was fixed or not, appreciated. The server is Dell r720xd, 128 GB RAM, plenty of disks and around 1 Gbit/s constant traffic. # lspci 00:00.0 Host bridge: Intel Corporation Sandy Bridge DMI2 (rev 07) 00:01.0 PCI bridge: Intel Corporation Sandy Bridge IIO PCI Express Root Port 1a (rev 07) 00:01.1 PCI bridge: Intel Corporation Sandy Bridge IIO PCI Express Root Port 1b (rev 07) 00:02.0 PCI bridge: Intel Corporation Sandy Bridge IIO PCI Express Root Port 2a (rev 07) 00:02.2 PCI bridge: Intel Corporation Sandy Bridge IIO PCI Express Root Port 2c (rev 07) 00:03.0 PCI bridge: Intel Corporation Sandy Bridge IIO PCI Express Root Port 3a in PCI Express Mode (rev 07) 00:05.0 System peripheral: Intel Corporation Sandy Bridge Address Map, VTd_Misc, System Management (rev 07) 00:05.2 System peripheral: Intel Corporation Sandy Bridge Control Status and Global Errors (rev 07) 00:11.0 PCI bridge: Intel Corporation Patsburg PCI Express Virtual Root Port (rev 05) 00:16.0 Communication controller: Intel Corporation X79 series chipset HECI Controller #2 (rev 05) 00:16.1 Communication controller: Intel Corporation X79 series chipset IDE-r Controller (rev 05) 00:1a.0 USB controller: Intel Corporation X79 series chipset USB2 Enhanced Host Controller #2 (rev 05) 00:1c.0 PCI bridge: Intel Corporation X79 series chipset PCI Express Root Port 1 (rev b5) 00:1c.7 PCI bridge: Intel Corporation X79 series chipset PCI Express Root Port 8 (rev b5) 00:1d.0 USB controller: Intel Corporation X79 series chipset USB2 Enhanced Host Controller #1 (rev 05) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev a5) 00:1f.0 ISA bridge: Intel Corporation X79 series chipset LPC Controller (rev 05) 01:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe 01:00.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe 02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe 02:00.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe 03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 01) 08:00.0 PCI bridge: Renesas Technology Corp.
