LKCD on 2.6 IA64 Linux Kernel

Hi all,

I tried using lkcd on a ia64 machine running on 2.6.5-7.111 SuSe Kernel for
debugging. I configured the swap device as the dump device and I created
panics,oops to generate dumps. The dump happens in /var/log/dump on a "lkcd
save" after a reboot. When I use lcrash to trace the task of the process
that caused the dump, I get some data misalignment errors as listed below.
And interestingly this happens only for the trace of the process that
generated the panic/oops. For all other processes in the dump trace is
giving me the proper output. Looks like the issue is specific to ia64 as I
did not encounter any such errors on my i386 machine on the same kernel. 
Pointers to any patches or what the problem is will be of help to me.

Can't find trace for running task!
