Bug Description
After creating a test crash (echo c > /proc/sysrq-
The system's root is not mounted, its block-device is not available under /dev.
Rebooting from there back to the normal system shows no dumped kernel under the configured /var/crash directory. /var/crash is part of the root fs, an ext4 mounted from /dev/nvme0n1p3
Expected behaviour:
echo c > /proc/sysrq-trigger
should give a kdump file in /var/crash
Actual behavior:
no file i /var/crash, a busybox shell in the kexec:ed kernel.
