And the ubuntu_zram_smoke_test regression test is failing due to the missing module. == Test == Before enabling CONFIG_ZRAM and the related configs, the zram module cannot be found. After that, the zram module can be inserted and pass the ubuntu_zram_smoke_test. Test kernels could be found here: http://people.canonical.com/~phlin/kernel/lp-1766823-zram/ == Fix == [bionic/linux-kvm][xenial/linux-kvm][SRU][PATCH] UBUNTU: [Config]: enable CONFIG_ZRAM == Regression Potential == Minimal. No code changes, just a config changes without disabling any other configs. ------ The ubuntu_zram_smoke_test will fail due to the lack of the zram module. 07:32:19 DEBUG| Running '/home/ubuntu/autotest/client/tests/ubuntu_zram_smoke_test/ubuntu_zram_smoke_test.sh' 07:32:19 ERROR| [stderr] modprobe: FATAL: Module zram not found in directory /lib/modules/4.15.0-1008-kvm 07:32:19 DEBUG| [stdout] FAILED: cannot load zram module 07:32:19 ERROR| Exception escaping from test: There is no zram config in the Bionic KVM kernel config file. $ grep -i zram debian.kvm/config/config.common.ubuntu $ ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-1008-kvm 4.15.0-1008.8 ProcVersionSignature: User Name 4.15.0-1008.8-kvm 4.15.17 Uname: Linux 4.15.0-1008-kvm x86_64 NonfreeKernelModules: signpost ApportVersion: 2.20.9-0ubuntu7 Architecture: amd64 Date: Wed Apr 25 07:32:47 2018 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-kvm UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1766823/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
