Kexec from 4.3 -> 4.3 works, but with the white-09.09.01-15.56 > petitboot (2.6.30.9) -> 4.3 gets a kernel panic: > > -> early_setup(), dt_ptr: 0x7fff000 > Kernel panic - not syncing: BUG: Failed verifying flat device tree, bad version? > > I'll look at it some more as I find time. That says that the device tree firmware gave you (ie. from kexec), is using an old version of the device tree format. I can't remember off the top of my head which version you need, but basically newer kernels require a newer device tree format. So your kexec might be too old? cheers
