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

I can not access the /proc/vmcore with crash or gdb.
In the source code, it can be in parse_crash_elf_headers,
parse_crash_elf64_headers or other, but I have no more messages from the
kernel.
How can I check that the elfcorehdr_addr has been passed correctly by
the crashed kernel ?
Did you already see this kind of problem ? Is there an other patch to
apply on the kernel or kernel.org is the only source to have kdump working ?

Thanks

Best regards

Benoit
