Bug Description
We've made some progress on bug 1499869 , such that on Friday I actually had successful installs.
An attempt at an install today shows a kernel stack trace early in the boot, then the initramfs not finding any network devices and thus failing to mount the iscsi root.
The trace looks like this:
