The v4.4.0-30 kernel is still available in the ppa: https://launchpad.net/ubuntu/xenial/+source/linux It might be good to test the v4.4.0-29 and v4.4.0-30 kernels. We can bisect between the two iv -29 is good and -30 is bad. To downloaded the kernels, click on the version number from that

We haven't tested v4.4.0-30 since there's no deb package for it (I guess it was removed from the repo?). -- 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/1622894 Title: sg devices are not

This bug does not exist in kernels prior to v4.4.0-30? If that is the case, we might be able to perform a kernel bisect to identify the commit that introduced the regression. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in

Hi, Amit is on vacation for the following week, so I ran the test again with '4.4.0-36-generic #55~lp1622894' and the sg device gets created when the alua driver is loaded: https://gist.github.com/2c1a1f9f81262fa8e490877e91bade95 but when I remove the lpfc driver there's still a stack trace in

I built a Xenial test kernel with a cherry-pick of commit 221255aee67. Can you test this kernel and see if it resolves this bug? It can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1622894/ With this kernel, you need to install both the linux-image and linux- image-extra .deb

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

apport information ** Tags added: apport-collected xenial ** Description changed: Most storage array expose a store controller device to logical unit 0. Following LP #1567602, when this happens and the alua driver is loaded, Ubuntu doesn't create the sg device for it, and linux fails to
