Yeah, it appears that the ARM backtrace code presumes that the dumpfile
was taken with the kernel's kdump facility, because it gets the backtrace
starting points from the register values save in the kdump "crash_notes".
Right, only the mainline kernel kdump is supported.
So you might try entering "bt -t" or "bt -T".
But if the cpus were
sitting in the idle state, there's probably not much to see.
One thing I do *not* like about the ARM "bt" display is that it
does not show the stack address of each frame. But I think the
ARM maintainers did it that way to simulate the kernel's log
output.
Exactly - we try to keep the resulting backtrace match what is printed to the
console and to the log.
