I think I am seeing a related behavior on my machine, and started to query the kubuntu forums on network support ( http://kubuntuforums.net/forums/index.php?topic=3105955.0 ), but maybe it's better placed here.
If you guide me a little bit (linux newbie, but computer-experienced), I'm willing to provide all information I can possibly retrieve from the system. Note that I have no network access from kubuntu, so I cannot install packages on the fly. SYSTEM HARDWARE + motherboard: MSI-7222 (VIA chipset), 2GB RAM installed (1GB recognized by Phoenix BIOS, seems a known bug) + ethernet adapter: RealTek RTL8139/810x Family Fast Ethernet NIC (as per windows), running fine in winXP. + graphics adapter: ATI Radeon HD 3450 (AGP 8x) + no other PCI devices SYSTEM SOFTWARE + WinXP running on one partition (with network access through dsl cable router), dual-boot system + Installed kubuntu 9.04 from iso image (-i386 live CD), downloaded 3 days ago. "Ubuntu 9.04, kernel 2.6.28-11-generic" + Removed network-manager-kde, trafficked /etc/network/interfaces, following advice in various forums + nothing else installed, since no network access SYMPTOMS + no network access through wired connection to cable router + various configurations in /etc/network/interfaces (dhcp, static) gave no result + trying to add router manually via route add ... was impossible [SIOADDRT: no such device] VAR/LOG/SYSLOG + shows I'm running realtek8139too + shows WATCHDOG NETDEV warning and trace + is attached (I can access winXP boot partition from kubuntu and save files there for uploading) APPORT-COLLECT + failed with the message Please install the package "python-launchpadlib". So, if there is anyone out there willing to tackle this problem together with me, I'm game... ** Attachment added: "syslog.startup.txt" http://launchpadlibrarian.net/30698952/syslog.startup.txt -- (net 8139too) system with two of these ethernet cards, under any reasonable load, generates NETDEV WATCHDOG: eth0: transmit timed out https://bugs.launchpad.net/bugs/229392 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
