[Kernel-packages] [Bug 1616107] Re: Kernel oops + system freeze on network-bridge shutdown
--- Comment From ru...@us.ibm.com 2017-04-06 17:50 EDT--- Sorry about the long delay, but our bridge missed the last two LP status updates. Validated with 4.4.0-72 and closing on our end. Thanks. ** Tags removed: targetmilestone-inin--- ** Tags added: targetmilestone-inin16042 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1616107 Title: Kernel oops + system freeze on network-bridge shutdown Status in bridge-utils package in Ubuntu: Invalid Status in linux package in Ubuntu: Fix Released Status in bridge-utils source package in Xenial: Invalid Status in linux source package in Xenial: Fix Released Status in bridge-utils source package in Yakkety: Invalid Bug description: A Kernel oops leaves Ubuntu 16.04 unusable when a network bridge is brought down on a HPE 530SFP+ 10GBit NIC that uses bnx2x as a driver.

[Kernel-packages] [Bug 1616107] Re: Kernel oops + system freeze on network-bridge shutdown
Based on the investigation so far, it seems to me that this is entirely a kernel bug, and there is nothing required in the bridge-utils package in order to fix this issue. So I'm marking this bug as Invalid for bridge-utils. The kernel tasks remain open. If this is incorrect, please explain why you expect to need a fix in bridge-utils and reopen that task. ** Changed in: bridge-utils (Ubuntu) Status: Confirmed => Invalid ** Changed in: bridge-utils (Ubuntu Xenial) Status: Confirmed => Invalid ** Changed in: bridge-utils (Ubuntu Yakkety) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1616107 Title: Kernel oops + system freeze on network-bridge shutdown Status in bridge-utils package in Ubuntu: Invalid Status in linux package in Ubuntu: Confirmed Status in bridge-utils source package in Xenial: Invalid Status in linux source package in Xenial: Confirmed Status in bridge-utils source package in Yakkety: Invalid Bug description: A Kernel oops leaves Ubuntu 16.04 unusable when a network bridge is brought down on a HPE 530SFP+ 10GBit NIC that uses bnx2x as a driver.

[Kernel-packages] [Bug 1616107] Re: Kernel oops + system freeze on network-bridge shutdown
We started a Reverse bisect in comment #17. However, it appears the hardware is no longer avaiable. As mentioned in comment #22, this is fixed in Yakkety. You could use that kernel, but if you can reproduce the bug, we can continue the reverse bisect? That would allow us to identify the commit that fixes the bug, and have it SRU'd to Xenial. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1616107 Title: Kernel oops + system freeze on network-bridge shutdown Status in bridge-utils package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in bridge-utils source package in Xenial: Confirmed Status in linux source package in Xenial: Confirmed Status in bridge-utils source package in Yakkety: Confirmed Bug description: A Kernel oops leaves Ubuntu 16.04 unusable when a network bridge is brought down on a HPE 530SFP+ 10GBit NIC that uses bnx2x as a driver.

[Kernel-packages] [Bug 1616107] Re: Kernel oops + system freeze on network-bridge shutdown
This bug affects me too. I'm working on a Tyan Power8 machine (PPC64el) with Ubuntu 16.04.1 and 10GB network cards using the bnx2x driver. A configured network bridge on my machine results in a kernel oops if I trigger a shutdown or reboot, see attachment. I installed the 4.8.0-040800-generic kernel and now the shutdown or reboot works fine, so I would recommend using the LTS Enablement Stack (linux-generic-lts-yakkety) when it's available. ** Attachment added: "shutdown-problem-power8" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1616107/+attachment/4753518/+files/shutdown-problem-power8 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1616107 Title: Kernel oops + system freeze on network-bridge shutdown Status in bridge-utils package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in bridge-utils source package in Xenial: Confirmed Status in linux source package in Xenial: Confirmed Status in bridge-utils source package in Yakkety: Confirmed Bug description: A Kernel oops leaves Ubuntu 16.04 unusable when a network bridge is brought down on a HPE 530SFP+ 10GBit NIC that uses bnx2x as a driver.

The #17 kernel has no oops. Network and bridge are brought up after boot, however there is no network connectivity on the bridge.

I started a Reverse kernel bisect between v4.4 final and v4.5-rc1. The kernel bisect will require testing of about 7-10 test kernels. I built the first test kernel, up to the following commit: 1289ace5b4f70f1e68ce785735b82c7e483de863 The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1616107 Can you test that kernel and report back if it has the bug or not?

Per comment #10, the bug was fixed somewhere between upstream 4.4 and 4.6. To narrow it down further, so we can perform a reverse bisect can you test the 4.5 final kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/ If 4.5 is good, maybe test 4.5-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-rc1-wily/ To perform the reverse bisect, we need to identify the last bad kernel version and the first good one. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1616107 Title: Kernel oops + system freeze on network-bridge shutdown Status in bridge-utils package in Ubuntu: New Status in linux package in Ubuntu: Confirmed Bug description: A Kernel oops leaves Ubuntu 16.04 unusable when a network bridge is brought down on a HPE 530SFP+ 10GBit NIC that uses bnx2x as a driver.

[Kernel-packages] [Bug 1616107] Re: Kernel oops + system freeze on network-bridge shutdown
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
