I have a System76 Pangolin Performance Pan-p4n with the same r8169 chipset problem. I've confirmed that this bug doesn't exist in Maverick 10.10 with the 2.6.35-28 kernel. The bug is in Maverick 2.6.35-30 and every Natty kernel I've tried up until 2.6.38-10. I found a temporary solution to stop the kernel panics in >2.6.35-28 kernels until the bug is fixed. Rate limiting the ethernet port to 100 mbps with ethtool seems to stabilize the system so far:
# install ethtool sudo apt-get install ethtool # turn off speed auto-negotiation and set speed to 100 mbps # note: plug in the ethernet cable first; setting is not persistent between reboots/network disconnects sudo ethtool -s eth0 autoneg off speed 100 # confirm setting sudo ethtool eth0 | grep -i speed To make this setting persistent, I added the following line to the end of /etc/network/if-up.d/ethtool /sbin/ethtool -s eth0 autoneg off speed 100 I also tried disabling active state power management by adding pcie_aspm=off to the grub boot options, but it didn't work, as it did for some Redhat users: https://bugzilla.redhat.com/show_bug.cgi?id=617936 ** Bug watch added: Red Hat Bugzilla #617936 https://bugzilla.redhat.com/show_bug.cgi?id=617936 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/784335 Title: Heavy network utilization with r8169 leads to kernel panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/784335/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
