------- Comment From peter.oberparlei...@de.ibm.com 2018-08-23 10:49 EDT------- I've installed cosmic on a DPM LPAR using the daily build ISO "cosmic-server-s390x.iso" (dated 2018-08-23). The installed system (kernel 4.17.0-7-generic, s390-tools 2.6.0-0ubuntu3) correctly applied auto-configuration data:
$ lsinitramfs /boot/initrd.img | grep zdev sbin/chzdev sbin/lszdev scripts/init-top/s390-tools-zdev $ sudo lszdev --auto-conf TYPE ID AUTO dasd-eckd 0.0.1000 yes dasd-eckd 0.0.1001 yes ... So that is working as expected. The install system on the other hand DID NOT correctly apply auto- configuration data - all device IDs needed to be input manually. Looking at the install system I found that kernel-support is available, but the initramfs logic that applies the kernel data (scripts/init-top/s390 -tools-zdev) is not present in the install initramfs: $ sudo mount cosmic-server-s390x.iso /mnt -o loop,ro $ lsinitramfs /mnt/boot/initrd.ubuntu | grep zdev sbin/lszdev sbin/chzdev It appears that the install system is not including initramfs scripts at all. @Canonical: What is the correct approach for extending the installer initramfs system to run the missing logic? -- 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/1776631 Title: [18.10 FEAT] I/O device pre-configuration Status in subiquity: New Status in Ubuntu on IBM z Systems: In Progress Status in debian-installer package in Ubuntu: New Status in linux package in Ubuntu: Fix Released Status in s390-tools package in Ubuntu: Fix Released Status in s390-tools source package in Bionic: New Bug description: I/O device auto-configuration is a mechanism by which users can specify IDs and settings of I/O devices that should be automatically enabled in Linux.
