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?

#5 Updated by Lukas Zapletal over 7 years ago

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.

#6 Updated by Lukas Zapletal over 7 years ago

When you are booting the image, can you stop at the bootloader and make a screenshot of all the options from kernel command line?

#7 Updated by Sachin Ghai over 7 years ago

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.

#8 Updated by Sachin Ghai over 7 years ago

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.

#9 Updated by Sachin Ghai over 7 years ago

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
