Hi, As you suggested, we have upgraded the kernel as per https://wiki.ubuntu.com/Kernel/MainlineBuilds?action=show&redirect=KernelMainlineBuilds and OS boots to the updated kernel properly on our cavium server Due to some issues with aarch64 kernel packages, the ‘build’ directory is missing under /lib/modules/<kver>/ after the update hence unable to build our smartpqi driver to retest this.
Please suggest how to upgrade to latest upstream kernel on aarch64 so that we can build our smartpqi storage driver. We have downloaded the following packages from http://kernel.ubuntu.com /~kernel-ppa/mainline/v4.18-rc5 and installed. linux-headers-4.18.0-041800rc5_4.18.0-041800rc5.201807152130_all.deb linux-headers-4.18.0-041800rc5-generic_4.18.0-041800rc5.201807152130_arm64.deb linux-image-4.18.0-041800rc5-generic_4.18.0-041800rc5.201807152130_arm64.deb linux-modules-4.18.0-041800rc5-generic_4.18.0-041800rc5.201807152130_arm64.deb Regards/Ram -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1781578 Title: Call trace observed while disabling PD on Ubuntu 16.04.4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1781578/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
