Re: Linux kernel crash dump

["Peter Teoh" <htmldeveloper@xxxxxxxxx>]

Just curious....

a.   What are the essential capabilities/features of kdump?   As far
as I know kdump is only a stacktrace, but systap tool can deliver
stack trace at many user-defined functions....and it has other
features to extract out the dynamic values of the variables....much
more powerful....

b.   Is the various memory snapshot tools provided by /proc fs and
/dev/*mem* not enough?   (/proc/vmstat, /proc/kcore (piped to xxd)),
/proc/iomem, /dev/mem (piped to xxd) etc)
