Red Hat Bugzilla – Bug 454898
Fedora LiveCD doesn't boot in Blu-Ray Drives.
Last modified: 2013-01-09 23:44:10 EST
Description of problem:
Blu-Ray Drives cannot successfully load the kernel in Fedora 8 and 9. They fail
on mounting the root fs, then dump to a bash shell where I am told to create a
symlink for /dev/root and exit the shell to continue the boot process.
Version-Release number of selected component (if applicable):
Broken for me in both 8 and 9.
Steps to Reproduce:
1. Boot a live cd off a Blu-Ray Device
Only tried on a Lite-On SATA 2x Blu-Ray combo CD/DVD/BD drive. On machines with
4xQC processors, 16GB RAM. Two duplicate machines each have this problem.

Relevant output of lsscsi --verbose -c:
Host: scsi0 Channel: 00 Target: 00 Lun: 00
Vendor: LITE-ON Model: BD B LH-2B1S Rev: AL09
Type: CD-ROM ANSI SCSI revision: ffffffff
Note: Device works fine under F9 when installed.
Can you get the output of lshal? And lsmod isn't in the sysreport for some
reason and could also be handy.
And is the drive connected to the internal sata (sata_nv)?
The drive is connected through a internal SAS port on the motherboard.
I'll get the output of lshal and lsmod sometime tomorrow.
For any other information you might need, please let me know by tomorrow, as
these machines have to ship out to MIT sometime tomorrow, they're not my
Hmm, might be a module that we're not including in the initrd then.
That's the biggest reason I can think of. When you're at the shell, you can
also check and see if /sys/block/sr0 exists (guessing not).
A little hard to guess what else might be useful, but I'm at least partially
convinced that it's a module not there now

Note: /sys/block/sr0 does not exist.
We didn't include mptsas in the list of modules in the initrd -- I've added it
to git and so the F10 images should have it
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. 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bug reports from releases that are no longer maintained.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 '9'.
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 9'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 9 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 please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
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.
The process we are following is described here:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
