[Bug 1570775] Re: makekdump should re-exec with cio_ignore on s390x
It is becoming unclear to me if the cio_ignore needs to be tied to a
bigger crashkernel value or not. I am preparing an update to kdump-tools
which will set the crashkernel value upon install. Right now, I'm
setting it to 196M for LPAR and 128M for zVM.
What should be the default values for LPAR and zVM ?
I will add a separate change to take the cio_ignore into account.

makekdump should re-exec with cio_ignore on s390x
Status in Ubuntu on IBM z Systems:
Status in makedumpfile package in Ubuntu:
We should re-exec with cio_ignore lines. As per report there, it
should result in lowered required crashdump setting.
Hypothetically, one should be able to test this imperially by lowering
crashdump memory settings until kdump does not succeed anymore. And
then generated and append `cio_ignore -k -u` to the
KDUMP_CMDLINE_APPEND= and see that kdump starts working again with a
lower memory usage.
Once this is developed / verified / tested, we should probably SRU
this back to xenial.
