https://bugzilla.novell.com/show_bug.cgi?id=427613 Summary: pcie r8169 network interface going up and down wildly since last kernel security update - 2.6.25.16-0.1-pae Product: openSUSE 11.0 Version: Final Platform: i386 OS/Version: openSUSE 11.0 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: abittner@stud.fh-heilbronn.de QAContact: qa@suse.de Found By: --- hello there, my opensuse 11.0 box was running pretty much flawlessly the recent months. on september 17th, i applied the latest kernel package that yast2 online_update offered me and my box ended up at: 2.6.25.16-0.1-pae i have a 04:09.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10) as eth2 which never gave me trouble so far. this eth2 is connected to a xdsl modem/bridge and does pppoe internet connection. so far so good. ever since this last kernel update i get loads of link up / link down events in /var/log/messages and this morning the whole dsl0 device was down. the last compressed messages log file from august only shows very few rtl8169 events at all, as this box simply boots up, brings up all the devices and conntects to the internet. eth2 never needs to get touched once its running: # bzcat messages-20080820.bz2 | grep -i "8169" -A 1 -B 1 | more Jun 30 09:45:23 linuxbox kernel: ip_tables: (C) 2000-2006 Netfilter Core Team Jun 30 09:45:23 linuxbox kernel: r8169: eth2: link up Jun 30 09:45:23 linuxbox kernel: 802.1Q VLAN Support v1.8 Ben Greear <greearb@candelatech.com> -- Jun 30 09:50:17 linuxbox kernel: ip_tables: (C) 2000-2006 Netfilter Core Team Jun 30 09:50:17 linuxbox kernel: r8169: eth2: link up Jun 30 09:50:17 linuxbox kernel: 802.1Q VLAN Support v1.8 Ben Greear <greearb@candelatech.com> -- Jul 8 21:02:28 linuxbox kernel: ip_tables: (C) 2000-2006 Netfilter Core Team Jul 8 21:02:28 linuxbox kernel: r8169: eth2: link up Jul 8 21:02:28 linuxbox kernel: 802.1Q VLAN Support v1.8 Ben Greear <greearb@candelatech.com> -- Jul 10 12:14:22 linuxbox kernel: ip_tables: (C) 2000-2006 Netfilter Core Team Jul 10 12:14:22 linuxbox kernel: r8169: eth2: link up Jul 10 12:14:22 linuxbox kernel: 802.1Q VLAN Support v1.8 Ben Greear <greearb@candelatech.com> -- Jul 28 19:44:54 linuxbox kernel: ip_tables: (C) 2000-2006 Netfilter Core Team Jul 28 19:44:54 linuxbox kernel: r8169: eth2: link up Jul 28 19:44:54 linuxbox kernel: 802.1Q VLAN Support v1.8 Ben Greear <greearb@candelatech.com> -- Aug 4 11:23:51 linuxbox kernel: ip_tables: (C) 2000-2006 Netfilter Core Team Aug 4 11:23:51 linuxbox kernel: r8169: eth2: link up Aug 4 11:23:51 linuxbox kernel: 802.1Q VLAN Support v1.8 Ben Greear <greearb@candelatech.com> ----------- so the next messages file is the current /var/log/messages: Sep 17 15:01:31 linuxbox kernel: r8169: eth2: link up Sep 18 18:49:37 linuxbox kernel: r8169: eth2: link down Sep 18 18:49:39 linuxbox kernel: r8169: eth2: link up Sep 18 20:10:59 linuxbox kernel: r8169: eth2: link down Sep 18 20:11:01 linuxbox kernel: r8169: eth2: link up Sep 18 20:15:49 linuxbox kernel: r8169: eth2: link down Sep 18 20:15:51 linuxbox kernel: r8169: eth2: link up Sep 18 20:50:15 linuxbox kernel: r8169: eth2: link down Sep 18 20:50:17 linuxbox kernel: r8169: eth2: link up Sep 18 20:54:09 linuxbox kernel: r8169: eth2: link down Sep 18 20:54:11 linuxbox kernel: r8169: eth2: link up Sep 18 21:04:06 linuxbox kernel: r8169: eth2: link down Sep 18 21:04:07 linuxbox kernel: r8169: eth2: link up Sep 18 21:04:48 linuxbox kernel: r8169: eth2: link down Sep 18 21:04:50 linuxbox kernel: r8169: eth2: link up Sep 18 21:07:52 linuxbox kernel: r8169: eth2: link down Sep 18 21:07:54 linuxbox kernel: r8169: eth2: link up Sep 18 21:14:38 linuxbox kernel: r8169: eth2: link down Sep 18 21:14:40 linuxbox kernel: r8169: eth2: link up Sep 18 21:17:12 linuxbox kernel: r8169: eth2: link down Sep 18 21:17:13 linuxbox kernel: r8169: eth2: link up Sep 18 21:18:12 linuxbox kernel: r8169: eth2: link down Sep 18 21:18:13 linuxbox kernel: r8169: eth2: link up Sep 18 21:20:09 linuxbox kernel: r8169: eth2: link down Sep 18 21:20:11 linuxbox kernel: r8169: eth2: link up Sep 18 21:28:48 linuxbox kernel: r8169: eth2: link down Sep 18 21:28:50 linuxbox kernel: r8169: eth2: link up Sep 18 21:31:46 linuxbox kernel: r8169: eth2: link down Sep 18 21:31:48 linuxbox kernel: r8169: eth2: link up Sep 18 21:34:51 linuxbox kernel: r8169: eth2: link down Sep 18 21:34:53 linuxbox kernel: r8169: eth2: link up Sep 18 21:36:08 linuxbox kernel: r8169: eth2: link down .... ------------- on september 17th, 2008, at 1500 i rebooted this machine as i updated the kernel reboot system boot 2.6.25.16-0.1-pa Wed Sep 17 15:01 (1+18:42) and ever since these messages start to appear... the internet connection works most of the time, but as i said before today it was down completely when i returned normally the eth2 nic reconnects to the internet during night at a 24hour cycle: Sep 8 04:15:02 linuxbox pppd[2804]: Connect time 1440.0 minutes. ..
