Bug#511334: debian-installer: S390 boot fails on Flex-ES machine

[Adam Thornton <adam@sinenomine.net>]

Package: debian-installer
Severity: important

S390 boot fails (sometimes just after detecting memory, sometimes after
detecting devices) on z/VM 5.2 and a Flex-ES machine.

Since there are reports of d-i working on z9 boxes, I suspect the issue
is that the kernel is built to exploit later System z functionality.  At
least for d-i the basic 31-bit-no-frills architecture should be selected
as the s390 kernel (and basic 64-bit for s390x, e.g. z900), with options
for kernels that exploit later additions to the architecture for
installation (ideally based on detected machine type).

Debian Release: 5.0
