[Bug 1705447] Re: misleading kernel warning skb_warn_bad_offload during checksum calculation
Hello, I still se this issue on Xenial with Kernel 4.4.0-93-generic #116-Ubuntu The server is bare-metal. It is just a cosmetic problem in the log files or I should upgrade as soon as possible ? I noticed the bad entries in my kern.log with my monitoring tool, but I dont see any side effect so far. Could anyone please clarify what is the operational impact of this bug ? thanks ! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1705447 Title: misleading kernel warning skb_warn_bad_offload during checksum calculation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1705447/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I built Xenial and Zesty test kernels with commit b2504a5dbef. The test kernels can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1705447 Can you test these kernels and see if they resolve this bug?
