Because Ok, I've cleaned them up heavily and pushed them here: https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git, branch rc6+0-sme-kdump However, testing on my zen box doesn't go as planned. And this is even before your patches. I load the kdump kernel with kexec-tools from the git-repo + the patch you mention: # ~/bpetkov/bin/sbin/kexec -p /boot/vmlinuz-4.19.0-rc6+ --initrd /boot/initrd-4.19.0-rc6+ --command-line="root=/dev/mapper/ubuntu--010236012132--vg-leap15 splash=silent showopts console=ttyS5,115200 console=tty0 debug ignore_loglevel log_buf_len=16M 1 irqpoll maxcpus=1 reset_devices vga=normal" verify that it has been loaded: # grep . /sys/kernel/kexec_* /sys/kernel/kexec_crash_loaded:1 /sys/kernel/kexec_crash_size:268435456 /sys/kernel/kexec_loaded:0 and then trigger the panic: # echo c > /proc/sysrq-trigger and I see the panic happening in the serial console but then nothing. The box resets instead. So something's still broken. Trying the kexec -l/kexec -e game works - the second kernel gets kexeced properly. -- Regards/Gruss, Boris.
