[Linux-ia64] Taking a dump while kernel panic

[Linux-ia64] Taking a dump while kernel panic

[Bruno Vidal]

	Hi.
I'm looking for something to take a dump when system panic.
I've found the patch from SGI to do that. But I'm asking if
there is something to take a dump in the IA64 project ?

	Thanks.

We (Mission Critical Linux) have a kernel patch which creates a
core dump on panic and also a tool (crash) which can be used to
analyze the resulting dump.  We're in the process of porting the
core dump patch to ia64; the crash tool has been ported to ia64
already.

We have some code that will do the dump on IA64 systems, so long
as you aren't using 64K page sizes.  If you'd like a patch for
this, let me know.  Note that this is against 2.4, not 2.3.99-preXX,
which is significant since some of the trace functionality had to
change.
