Unable to run lcrash on dump got.

[Priti Rathi]

Hello All,
I got some dumps. But I am unable to analyze it using lcrash.
The lcrash does not go to lcrash prompt. After initializing arch
specific data ,the lcrash quits execution.
====

Prompt> cat analysis.7

Initializing vmdump access ... Done.
Loading system map ... Done.
Loading type info (Kerntypes) ... Done.
Initializing arch specific data ... Done.Prompt>

========

Can anyone suggest me what kind of changes require in kernel to analyze
these dumps?

Looking forward for reply,
Thanks,
-Priti
