Description Tim Flink 2012-02-21 20:59:19 UTC
I copied the F17 Alpha RC3 x86_64 DVD iso to an 8G USB drive with dd.

When I attempt to boot that usb image, I have no problems getting to the syslinux prompt but when I attempt to boot into the installer, I get a grey flashing screen with the error message:

uncompression error

 -- system halting

Comment 1 Tim Flink 2012-02-21 21:00:30 UTC
I was able to work around this bug by installing syslinux-4.05-1 and running isohybrid on the iso (no arguments) before using dd to write the iso to disk

0) The Alpha DVD iso linked to from the homepage currently is http://download.fedoraproject.org/pub/fedora/linux/releases/test/17-Alpha/Fedora/x86_64/iso/Fedora-17-Alpha-x86_64-DVD.iso . I have no idea whether that is RC3 or not.

1) That image is a hybrid iso image. It can be booted (in qemu-kvm) either as a hard disk image or as a DVD disc image.

2) Could it be that the "F17 Alpha RC3 x86_64 DVD" iso that Tim used was originally made hybrid using (current F16) syslinux-4.02-5? Could it further be that using isohybrid from syslinux-4.05-1 (for the second time!) on that iso somehow changed the way that hybrid iso booted in hard disk mode, allowing Tim to boot it from USB disk?

Just to be complete: those should be kernel messages. See currently (ie, v3.4-rc3):
    lib/decompress_inflate.c:159:                   error("uncompression error");

and
    arch/x86/boot/compressed/misc.c:270:    __putstr(1, "\n\n -- System halted");

Comment 4 Fedora End Of Life 2013-07-04 02:36:17 UTC
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 5 Fedora End Of Life 2013-08-01 08:49:30 UTC
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
