OK, I was hoping that perhaps it would show up after the cpu and cpu_common devices, because if that were the case, we could just bail out on reading any more devices. > I also got this on stderr: > > ------------------------------------------------------------ > WARNING: Because this kernel was compiled with gcc version 4.4.5, certain > commands or command options may fail unless crash is invoked with > the "--readnow" command line option. > ------------------------------------------------------------ > That debug message is essentially harmless/useless. There was a gcc version in the 3.4.0 timeframe that required the embedded gdb to have --readnow passed to it in order to gather the required debuginfo data. It was fixed subsequently, although I'm not sure in which gcc version. I should probably at least cap the message at gcc 4.x.x or something like that.
