I'm confused, 5.13 is not the Jammy kernel, that was a transitional kernel version. Can you actually recreate this on Jammy using the released 5.15 kernel?
And does it occur on the latest dev release (Kinetic)? You'll need to install the 22.10 (Kinetic) image, and then enable the propsoed repo and update the kernel to get the 5.19 kernel from -proposed: linux-image-generic | 5.19.0.15.15 | kinetic-proposed | amd64, arm64, armhf, ppc64el, s390x -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.13 in Ubuntu. https://bugs.launchpad.net/bugs/1960324 Title: [VROC] Kernel does not contain fixes for iostat for md devices Status in linux package in Ubuntu: Invalid Status in linux-hwe-5.13 package in Ubuntu: In Progress Status in linux source package in Focal: Invalid Status in linux-hwe-5.13 source package in Focal: In Progress Status in linux source package in Impish: Won't Fix Status in linux-hwe-5.13 source package in Impish: Invalid Bug description: Hello, I noticed that kernel which was used in ubuntu 22.04 (hwe-5.13) does not contain fixes for IO statistics for md devices.
