** Description changed: The following issue occured several times over the last month with Ubuntu 11.10 x86_64, kernel 3.0.0-16-generic. It happened from the beginning (3.0.0-15). I didn't have this Computer before, so I don't know if the issue is specific to this Ubuntu / kernel version. Sometimes, after waking up from suspend, single remote hosts are not reachable. It may be the first host the system tries to connect to (or may be the last one connected to before susped), but I'm not sure about that. "not reachable" means there's no route. It's not a DNS issue because trying to ping the IP itself also fails. Example ping output: $ ping 80.237.133.28 PING 80.237.133.28 (80.237.133.28) 56(84) bytes of data. From 78.104.151.116 icmp_seq=1 Destination Host Unreachable ... at the same time: $ ping google.com PING google.com (209.85.148.139) 56(84) bytes of data. 64 bytes from fra07s07-in-f139.1e100.net (209.85.148.139): icmp_req=1 ttl=57 time=15.3 ms ... here, 78.104.151.116 is my own IP in this network. The destination IP is definitely reachable, I can reach it at the same moment on a different machine in the same network. Or from my own machine if I first ssh to another machine and connect from there. The issue is hardly a network interface driver issue, because this already happened with both WiFi and Ethernet connection. It looks like the issue doesn't happen in all networks. In my home network it didn't happen yet, but already in two other networks. I don't know what makes the difference. As I said, the issue is isolated to single destination hosts. At the same time, the connection works normally for all other destinations. I could solve this only by reboot up to now. Things I tried: - restart networking - suspend / wakeup again - disconnect / reconnect network interface - switch network interface (WiFi / Ethernet) - ip route flush cache - ip neigh flush all I am no networking expert, but a sysadmin of the university network took a look at my Computer when the issue appeared. He couldn't find out the reason, but suspected it to be a kernel issue. I think the posting at http://askubuntu.com/questions/100717/some-ips- unreachable-after-resume-from-suspend describes the same issue, but I didn't get any further feedback there. - For any further advice on how I could gather more useful information / - try to fix it I would be very helpful. + For any further advice on how I could gather more useful information / try to fix it I would be very helpful. + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24. + ApportVersion: 1.23-0ubuntu4 + Architecture: amd64 + ArecordDevices: + **** List of CAPTURE Hardware Devices **** + card 0: Intel [HDA Intel], device 0: CONEXANT Analog [CONEXANT Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: didi 6739 F.... pulseaudio + /dev/snd/pcmC0D0p: didi 6739 F...m pulseaudio + CRDA: Error: [Errno 2] Datei oder Verzeichnis nicht gefunden + Card0.Amixer.info: + Card hw:0 'Intel'/'HDA Intel at 0xf2520000 irq 43' + Mixer name : 'Intel IbexPeak HDMI' + Components : 'HDA:14f15069,17aa21a4,00100302 HDA:80862804,17aa21b5,00100000' + Controls : 12 + Simple ctrls : 6 + Card29.Amixer.info: + Card hw:29 'ThinkPadEC'/'ThinkPad Console Audio Control at EC reg 0x30, fw 6UHT32WW-1.13' + Mixer name : 'ThinkPad EC 6UHT32WW-1.13' + Components : '' + Controls : 1 + Simple ctrls : 1 + Card29.Amixer.values: + Simple mixer control 'Console',0 + Capabilities: pswitch pswitch-joined penum + Playback channels: Mono + Mono: Playback [on] + DistroRelease: Ubuntu 11.10 + EcryptfsInUse: Yes + InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) + MachineType: LENOVO 29124NG + Package: linux (not installed) + ProcEnviron: + LANGUAGE=de_AT:de + PATH=(custom, user) + LANG=de_AT.UTF-8 + SHELL=/bin/bash + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.0.0-16-generic root=UUID=e56748e9-2b6d-4d64-81e2-cd1f2a6ab6d6 ro quiet splash vt.handoff=7 + ProcVersionSignature: Ubuntu 3.0.0-16.29-generic 3.0.20 + RelatedPackageVersions: + linux-restricted-modules-3.0.0-16-generic N/A + linux-backports-modules-3.0.0-16-generic N/A + linux-firmware 1.60 + StagingDrivers: mei + Tags: oneiric staging + Uname: Linux 3.0.0-16-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm admin cdrom davfs2 dialout lpadmin plugdev sambashare + dmi.bios.date: 05/10/2011 + dmi.bios.vendor: LENOVO + dmi.bios.version: 6UET64WW (1.44 ) + dmi.board.name: 29124NG + dmi.board.vendor: LENOVO + dmi.board.version: Not Available + dmi.chassis.asset.tag: No Asset Information + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: Not Available + dmi.modalias: dmi:bvnLENOVO:bvr6UET64WW(1.44):bd05/10/2011:svnLENOVO:pn29124NG:pvrThinkPadT410s:rvnLENOVO:rn29124NG:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: + dmi.product.name: 29124NG + dmi.product.version: ThinkPad T410s + dmi.sys.vendor: LENOVO ** Attachment added: "AcpiTables.txt" https://bugs.launchpad.net/bugs/956918/+attachment/2881389/+files/AcpiTables.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/956918 Title: Single IP unreachable after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/956918/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
