I did not got a full boot log due to efi issues, but I think it works for me
as for this cache issue.

For UEFI, seems you applied Ard's original efi stable mapping patch, but he
has an update version which solves fw_vendor panic etc. I tried but the patchset
can not apply on your tree.

I will have no time to test and work on kexec issues this week. Will try next week
with more testing.

Thanks
Dave
