Hello,

I am using kernel version 2.6.34.4 and trying to enable kernel crash using kexec (kdump). Every time the crash occurs, the size of the dump file (vmcore) is incomplete (around 20 MB).OS is installed with 8 GB of RAM. Due to this gdb/crash fails to analyze the core dump.

Does anyone know where to look for this issue? Is there any known issue with this kernel version or any fix available?

Regards,
Ritesh.
