I can understand why you suggest that, but why does Fedora 14 work? The
failure appears to occur during the kernel start up and Fedora 15 has a
newer kernel, for Live CD, install DVD, and actual installation, and all
fail appear to fail during kernel start up. Perhaps after Fedora 15 has
the next kernel update another install will work.

I remember from one of your previous posts that you have a SCSI
controller and some device attached in your machine (it was also visible
in your smolt profile, IIRC). What is that and what do you have attached
there?

[snip]

I can suggest the following. Disconnect the SCSI device and try the F15
Live KDE. Does it work? If not, please send some info on where and how
it stops (take a picture of the screen, write down what you see on a
paper and retype in an e-mail, whatever). Continue disconnecting all
unnecessary hardware. The only thing you *need* in a machine is memory,
one hard disk, one CD/DVD drive and a video card (and obvious stuff ---
a motherboard, processor, power supply, keyboard and monitor). Remove
everything else, and try to boot the F15 Live KDE.

[snip]

A very important point --- *please* send us *detailed* information on
where, how and what fails to work. If you don't have the technical
skills to explain the details yourself, take a photo of a screen with a
failed boot attempt, and post it. You can use a camera built into your
mobile phone (or ask a friend for one), and you can use a working F14 to
put it online.

Well I agree that my opinion posts were made out of frustration, wrongly.

If you look at some of my other posts here you will see that I have
provided further details that detail that the Fedora 15 install DVD,
Fedora 15 Live KDE CD, and a Fedora 15 install, (by other means), all
fail in a similar manner, which appears to be requiring multiple SCSI
reset bus, then core dump, and shows various Advansys calls.

Ok, so social things aside, have you tried to disconnect the SCSI device and
boot the F15 Live KDE? What is the result?

Also, you still didn't say which device is attached to the SCSI controller and
what is it used for? Is it a hard disk? A DVD drive? Network equipment?
Something else? Detailed hardware specs could be useful, because someone may
be aware of a potential kernel/driver bug for that particular device, or maybe
know a workaround. Post as many details as you can about it.

Given that the boot process hangs with a SCSI bus reset, I have a feeling that
this device is the culprit of your problems. Another piece of info would be
useful --- where in the boot process does the SCSI bus reset message appear?
Is it during the kernel booting phase, or after init kicked in? Is the root
partition already remounted r/w, or is it still mounted read-only? If it is
still read-only, there will be no info in the logs. But if it happened after
the r/w remount, you can mount the F15 / partition into some directory of F14,
and look at /mountpoint/var/log/messages and /mountpoint/var/log/boot.log for
further info (/mountpoint is the name of the directory in F14 tree where you
have mounted the F15 / directory).

Any of those things would be helpful in diagnosing what goes wrong during the
boot. But above all, do try to disconnect the SCSI device altogether and boot
into F15. If that works, do a yum update and see if it pulls in a new kernel,
then reattach the device and try again with the latest kernel. Maybe the
drivers had a bug.

Come back with as much info as you can collect about this.

HTH, :-)

Currently nothing is attached to the SCSI controller. So I'm wondering
if I actually remove it, the problem will disappear.

I'm fairly sure the Fedora 15 install is mostly up to date, as I
installed direct from the Fedora repos, release and updates.

The SCSI bus reset is in the kernel booting phase I believe.
