Hello all,
I try kdump with 2.6.20-rc4 kernel from kernel.org.
I successfully reboot on the debug kernel after c sys-rq but I have an
error :
Kdump: vmcore not initialized
Were exactly are you seeing that message?
And as a stab in the dark, is CONFIG_PROC_VMCORE (and CONFIG_CRASH_DUMP)
enabled in your dump-capture kernel?
This message appears during the boot of the second kernel (dmesg | grep
Kdump).
And of course, VMCORE is activated in the kernel.
Do you have any other idea about this problem ?
Can you post whole of the boot logs of second kernel?
Thanks
Vivek

So I have no more error messages. The error can occurs anywhere.
I have dumped the old memory at the trusted elfcorehdr : 1572608K.
How can I analyse this data ? Where are define the ELF headers ?
Thank you for your answers.
Regards,
Benoit
