I pushed out a kexec-v12.1 branch to my linux-kexec repo [1] with
fixes.  Could you test it with both kexec reboot and kdump?  For
kdump, use something like:

  CMDLINE += 'crashkernel=64M@2240M'

then

  # kexec -d --load-panic /boot/vmlinux.strip --append="1 mem=64M maxcpus=1 reset_devices console=... root=..."
  # echo c > /proc/sysrq-trigger

We need to test both reboot and kdump since the the way the kexec is
done is different for the two.

I pushed out a kexec-v12.1 branch to my linux-kexec repo [1] with
fixes.  Could you test it with both kexec reboot and kdump?  For
kdump, use something like:

  CMDLINE += 'crashkernel=64M at 2240M'

then

  # kexec -d --load-panic /boot/vmlinux.strip --append="1 mem=64M maxcpus=1 reset_devices console=... root=..."
  # echo c > /proc/sysrq-trigger
