Other reviewers? So I'm testing this on a box with SME enabled but after loading the crash kernel, it freezes instead of rebooting. My cmdline is: kexec -s -p /boot/vmlinuz-5.2.0-rc3+ --initrd=/boot/initrd.img-5.2.0-rc3+ --command-line="maxcpus=1 root=/dev/sda5 ro debug ignore_loglevel log_buf_len=16M no_console_suspend net.ifnames=0 systemd.log_target=null mem_encrypt=on kvm_amd.sev=1 nr_cpus=1 irqpoll reset_devices vga=normal LANG=en_US.UTF-8 earlyprintk=serial cgroup_disable=memory mce=off numa=off udev.children-max=2 panic=10 rootflags=nofail acpi_no_memhotplug transparent_hugepage=never disable_cpu_apicid=0" and the reserved range is: [ 0.000000] Reserving 256MB of memory at 3392MB for crashkernel (System RAM: 16271MB) I'm wondering if it is related to https://lkml.kernel.org/r/20190604134952.GC26891@MiWiFi-R3L-srv Thx. -- Regards/Gruss, Boris.
