Hi Geoff, > 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' For kdump, I also require a version of the patch "arm64/kexec: Add support for kexec-lite". Without this, the dump capture kernel cannot find the device tree even on v11 that I tested. Thanks, Azriel Samson Qualcomm Innovation Center, Inc.
