Re: Help needed for analysing kernel core dump

HI everyone,

I'm trying to look into kernel core dump,

the core dump is placed in /var/crash

to use kdump it needs vmlinux in centos coud not find it also there is no directory debug as suggested in one of links

crash /usr/lib/debug/lib/modules/crashed-kernel-version/vmlinux /path-to-the-vmcore

Do i need to make a fresh kernel code compilation with debug mode set on? or can i download from any source the vmlinux for i386.

I could see in boot directory vmlinz can i generate the vmlinux is both same.

Please provide your valuable inputs 
Thanks
Santosh

Re: Help needed for analysing kernel core dump

You're running a PAE kernel, but don't have the PAE debuginfo package...  Those
are named "kernel-PAE-debuginfo*"...

Update: D'oh!  Nevermind, I totally missed that last RPM you show, which is the
PAE debuginfo...  Ok, then, is that maybe in a different directory than the one you
are trying to use?  I'd expect it to have the "PAE" in the kernel version directory...
