I can reproduce, but only when booting this via "Test this media & Start Fdi" option which is not default. We will not block the release I think, if you confirm this behavior.
I spent some time to figure out the reported issue and realized that issue appears only with unmodified FDI-bootable-3.0.2.iso image. If I boot system with re-mastered iso then issue doesn't appears.
Also, on side note, I pxe booted a EFI system and got shell> prompt on start-up. Is it expected ? does this require special configuration?
Just for the record, the MD5 sum does not seem to be correct in that file, but it works for me. Can you confirm it works?
[lzap@lzapx isos]$ md5sum fdi-bootable-3.0.2.iso
bac70149a72752e00d06240b6a9ed95b fdi-bootable-3.0.2.iso
[lzap@lzapx isos]$ checkisomd5 fdi-bootable-3.0.2.iso
Press [Esc] to abort check.
The media check is complete, the result is: FAIL.
It is not recommended to use this media.
When you are booting the image, can you stop at the bootloader and make a screenshot of all the options from kernel command line?
Yeah.. same output while checking the md5sum of ISO..
[root@cloud-qe-19 ~]# checkisomd5 fdi-bootable-3.0.2.iso
Press [Esc] to abort check.
The media check is complete, the result is: FAIL.
It is not recommended to use this media.
But when I boot the VM with this ISO, I end-up with media_failure error as shown in screenshot. I believe its failing before booting since validation of media doesn't pass.
Reported issue is reproducible with unmodified fdi-bootable-3.0.4.iso. However, If I boot an EFI system with remastered ISO then that works without any issue.
Checksum result of remastered ISO is NA
==========================================
[root@cloud-qe-17 ~]# checkisomd5 fdi-bootable-3.0.4-151109_064031.iso
Press [Esc] to abort check.
The media check is complete, the result is: NA.
No checksum information available, unable to verify media.
Checksum result of unmodified is FAIL
===================================
[root@cloud-qe-17 ~]# checkisomd5 fdi-bootable-3.0.4.iso
Press [Esc] to abort check.
The media check is complete, the result is: FAIL.
It is not recommended to use this media.
Note: I'm using fedora23 to create EFI system
