Hi,

I forgot to mention that i ran kexec with these parameters:
[root@holism redhat]# kexec -p <dump-capture-kernel> \
  --initrd=,initrd-for-dump-capture-kernel> \
  --append="root=LABEL=/ init 1 irqpoll console=ttyS0,38400n8 maxcpus=1"
[root@holism redhat]#

The command was executed without an error or warning.

Thanks,
