backporting kexec/kdump function

[larry.brigman at gmail.com (Larry Brigman)]

I would like to get the list's opinion about
which kernel tree I should use to backport the
kexec/kdump functionality into
a Montavista 2.6.10 kernel tree.

I am in a project that is wed to the MVL tool chain/kernel tree for now. MVL
isn't going to support this function until about the middle of next
year (2.6.16 kernel).

I believe that I have functional change sets (which none apply
cleanly) from 2.6.9 through
2.6.12.

I have actually been able to get this partially working from the
2.6.9-mm1 but it
doesn't get me a valid core dump (kexec -e and kexec -p both work).
The file is marked correctly as a core but it is the size of all
memory and gdb determine
anything about the file. The lastest version of crash (with and outof
data gdb) doesn't
understand the file either.

I am using the kexec-tools-1.101 with the kdump patch and gcc 3.4.3.

Also, is there other resources I should be looking at to examine the core dump.

thank you for your time,
