The machine is a router/NAT box, crammed full of NICs, running IPTables but not much else. It's an MSI C847MS-E33 board (fanless low power Dual core Celeron), with PCIe and PCI slots; it's PCI slots have a dual e100 (Compaq NC3134 card) and a quad Tulip (HP A5506B) <-------------------- Failing setup: --------------------> MSI C847MS-E33 motherboard 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 7 Series/C210 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #2 (rev 04) 00:1c.0 PCI bridge: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 1 (rev c4) 00:1c.1 PCI bridge: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 2 (rev c4) 00:1c.2 PCI bridge: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 3 (rev c4) 00:1c.3 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev c4) 00:1d.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation 7 Series Chipset Family LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation 7 Series Chipset Family 6-port SATA Controller [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation 7 Series/C210 Series Chipset Family SMBus Controller (rev 04) 04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

On one Tulip is a switch and a pair of different vendors IP cameras; when watching one of them (but not the other!) in a webbrowser on either of the e100's (ethd or eth2d) the e100 stops receiving or sending any packets after a few seconds, and if I turn tx_err on I see: Feb 2 01:02:22 gort2 kernel: [ 490.393485] e100 0000:08:05.0 ethd: exec cuc_dump_reset failed Feb 2 01:02:44 gort2 kernel: [ 512.059435] e100 0000:08:05.0 ethd: exec cuc_dump_reset failed Feb 2 01:02:47 gort2 kernel: [ 514.729514] IPv6: ADDRCONF(NETDEV_UP): ethd: link is not ready Feb 2 01:02:47 gort2 kernel: [ 514.733515] e100 0000:08:05.0 ethd: NIC Link is Up 100 Mbps Full Duplex Feb 2 01:02:47 gort2 kernel: [ 514.733658] IPv6: ADDRCONF(NETDEV_CHANGE): ethd: link becomes ready There is no corresponding Link is Down prior to that - the cuc_dump_reset fail is the 1st indication of a problem. (This is with both 3.8 and 3.11) * Without the stream to that particular camera the e100's are happy - survived for a few weeks doing package installs, normal browsing etc * Moving my subnet off the e100 onto one of the other Tulip ports and it's happy. - looking at that cameras stream on the Tulip seems to allow the other e100 to carry on working fine, but that's less heavily tested * The only difference I can see from a network point of view between the two cameras is that the one that triggers the problem tends to send 1440 byte packets, the other only sends 900 byte packets (at a higher level their mostly just jpeg in a browser) * With the default BIOS PCI latency of 32 it fails after a few seconds of viewing the video off the camera, with 128 it survives to about 10mins or more but will fail eventually. * When it fails, an ifdown/ifup on the e100 in question restores it to sanity until I look at that camera again. * Note the dual and quad cards are PCI-x cards in 32-bit PCI slots (which they claim to support as far as I can tell) * The failure mode is reliable - there are no random failures. * I see there was a known problem on that ASMedia bridge with it losing interrupts, but a search suggests that was resolved on the rev3 I have. What gets me most about this is the way it's so specific to make it fail, but I guess it's just down to bus activity. Any suggestions welcome.
