But first I'll fix the header format which _is_ different in
crash and
our SLES9 kernel (and klcdutils), and if it then doesn't work I'll
come back to the system maps.
Thanks for your help!

Bernhard,
There are two changes rquired to fix up the header format for SLES9.
One is NR_CPUS and the other is a missing fiels in the dump header.
This may be of help, it' what I've been using:

Sorry for the late reply ... :)
I hacked a patch that does that dynamically. The issue is that
lkcd's lcrash _doesn't_ have that problem because it reads all offsets
of that structure dynamically from kerntypes (the kernel has the same
structures) while crash does that statically.
However, that patch at least works for both SLES-10 and SLES-9 kernels
on IA-64 (I don't know why the position of dha_kernel_addr was
changed, sorry :)) and is better than recompiling crash. Maybe it also
helps you. It will be included at least in openSUSE 10.3 packages.

Hi Bernhard,
I'm not sure whether you're requesting that this patch be applied in
the mainline version or not?
In any case, if it is, I'll let my LKCD-ia64 maintainer (troy.heber(a)hp.com)
open the gate.
Troy?
Thanks,
Dave

I think it's too specific (the part that detemines the position of the
load daddress), but at least I think the LKCD IA64 maintainer should
take a look at the problem that CONFIG_NR_CPU in kernel must be equal
to the CPU define in crash and find a solution for this.

Bernhard

I agree, the patch is to specific. I also like the NR_CPU calculation.
Bernhard, can you workup a patch that just does the NR_CPU calc and
skips the header moves?

Attached. The dha_kernel_addr member is now also upstream in
http://lkcd.svn.sourceforge.net/svnroot/lkcd/trunk/lkcd/lkcd-8.0.0_rc5_2....
