kdump/kexec/crash on vmcore file

Hi, all. This is my first attempt to troubleshoot a kernel panic so I
am quite newbie in this area. I have been able to obtain a kdump when
my box had kernel panic.
I set up Kdump and Kexec and then the captured/crash kernel to boot
into Level 1 and then copy /proc/vmcore file to the disk for later
analysis. However, after the server booted back to Level 3 and I
utilized the crash command to analyzed the vmcore file. I got error
message:
./crash /boot/vmlinux ../vmcore.test
crash: read error: kernel virtual address: ffffffff8123d1e0 type:
"kernel_config_data"
WARNING: cannot read kernel_config_data
crash: read error: kernel virtual address: ffffffff813b5180 type: "xtime"
I installed the lastest crash software 4.0-3.6. I googled left and
right but nothing has turned up useful.
Thank you for all the helps and hints.
My box is dual Xeon 3.2 GHz, 4 GBs of PC2700 DDR2 and run CentOS 4.3
