Hi, I have test your PATCH in Qemu guest: ---------- Fedora 29 (Workstation Edition) Kernel 5.1.0-rc3+ on an x86_64 (ttyS0) localhost login: root Password: Last login: Tue Apr 2 05:30:33 on ttyS0 [root@localhost ~]# cd /boot [root@localhost boot]# ls config-4.18.16-300.fc29.x86_64 efi extlinux grub2 initramfs-0-rescue-858ff1f5d0cb453898ae6c7f77c68ba7.img initramfs-4.18.16-300.fc29.x86_64.img initramfs-4.18.16-300.fc29.x86_64kdump.img initramfs-5.1.0-rc3+.img initramfs-5.1.0-rc3+kdump.img loader lost+found System.map System.map-4.18.16-300.fc29.x86_64 System.map-5.1.0-rc3+ vmlinuz vmlinuz-0-rescue-858ff1f5d0cb453898ae6c7f77c68ba7 vmlinuz-4.18.16-300.fc29.x86_64 vmlinuz-5.1.0-rc3+ [root@localhost boot]# kexec -l vmlinuz-5.1.0-rc3+ --initrd=initramfs-5.1.0-rc3+.img --reuse-cmdline [root@localhost boot]# kexec -e [ 77.933760] Unregister pv shared memory for cpu 1 [ 77.933763] Unregister pv shared memory for cpu 2 [ 77.933766] Unregister pv shared memory for cpu 5 [ 77.933825] Unregister pv shared memory for cpu 7 [ 77.933882] Unregister pv shared memory for cpu 3 [ 77.933904] Unregister pv shared memory for cpu 8 [ 77.936147] Unregister pv shared memory for cpu 4 [ 77.936199] Unregister pv shared memory for cpu 9 [ 77.945822] Unregister pv shared memory for cpu 0 [ 77.946308] Unregister pv shared memory for cpu 6 [ 77.947420] sd 0:0:0:0: [sda] Synchronizing SCSI cache [ 77.989030] kexec_core: Starting new kernel early console in extract_kernel input_data: 0x000000017f6033b1 input_len: 0x00000000008412d4 output: 0x000000017e000000 output_len: 0x0000000001e15844 kernel_total_size: 0x0000000001e2c000 trampoline_32bit: 0x000000000009d000 booted via startup_64() Physical KASLR disabled: no suitable memory region! ------ I am not sure whether I have done the right test. This guest is booted from EFI. Here we can see the kexeced kernel has completed the compressed boot stage. So I think your PATCH works.
