It looks likely this is related to bug #326891 "2.6.27.11 kernel breaks r8169 support for rtl8102e". The fix for that issue was to introduce five patches that correct the handling of the various realtek devices. Some devices are recognised by PCI ID and some by their MAC, with work- arounds for the "unknown MAC" issue (reported in the dmesg log).
Apparently this caused code meant for the 8169 to be executed for other devices which shouldn't have been used I suspect maybe there is a transmit-side issue remaining to be patched. Looking at all the upstream and other-distribution bug reports it seems to be a widespread issue. -- network device, module r8169, fails with NETDEV WATCHDOG: eth0: transmit timed out https://bugs.launchpad.net/bugs/76489 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
