How about the 4.4 kernel? And are they using a normal HDD/SSD for the root filesystem, or are they using a NVMe of some sort?
I'm currently following another bug where the memory test fails reliably when using an NVMe as the root filesystem but passes when a SSD or HDD is used. In that case, 4.4 can pass, but 4.15 and 4.18 fail. -- 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/1796217 Title: Qunata server memory stress cause "rcu_sched detected stalls on cpus/tasks" Status in linux package in Ubuntu: Incomplete Status in linux source package in Bionic: Incomplete Bug description: We are facing a problem during the certification test.
