Description of problem: after executing preupgrade (on f14) Version-Release number of selected component (if applicable): I'm not sure, if this is really preupgrade related preupgrade-1.1.8-1.fc14.noarch How reproducible: every time, different systems Steps to Reproduce: 1. preupgrade to f15 2. reboot to install system 3. Actual results: install system shows black screen, blinking cursor. Expected results: boot into anaconda to install/upgrade system Additional info: tried this in virtual box and on real (not ancient, about 3 years old) hardware. /boot/upgrade/vmlinuz and /boot/upgrade/initrd get installed, grub entry is written, it looks ok.
I discovered that on my machine, although it looks to be doing nothing, it does actually work after a while.
Latest version of preupgrade (1.1.9) fixes this.
