Hello, Before commiting this into the new kdump-tools, let me confirm with you :
The current use has the following kexec command (from kdump-config show) : kexec command: /sbin/kexec -p --command-line="root=/dev/mapper/vg_ubuntu-root BOOT_IMAGE=0 irqpoll maxcpus=1 nousb systemd.unit=kdump-tools.service" --initrd=/var/lib/kdump/initrd.img /var/lib/kdump/vmlinuz Your suggestion is to have the following kexec command : kexec command: /sbin/kexec -p --command-line="root=/dev/mapper/vg_ubuntu-root BOOT_IMAGE=0 irqpoll maxcpus=1 nousb systemd.unit=kdump-tools.service cio_ignore=all,!0009,!0200,!0600-0602" --initrd=/var/lib/kdump/initrd.img /var/lib/kdump/vmlinuz I have implemented this by adding the cio_ignore statement (from cio_ignore -k -u) to the KDUMP_CMDLINE_APPEND statement in /etc/default /kdump-tools file if installed on s390. This differs from the statement in https://wiki.ubuntu.com/S390X that says that it should be added to /etc/zipl.conf and, hence applied to any running kernel, not only the one that is kexec'd.
