addiciton info:

amd xp 2000+
nvidia geforce 5200
hdd: 
30gb at ide controller
40gb and 80gb at raid controller but used as ide controller
250gb at sata controller

perhaps because of harddisk configuration?

Can you switch ttys in text mode when it hangs?  Are your keyboard LEDs flashing?

have no keyboard leds (wireless keyboard)

i'm able to stwitch ttys...

in tty3 the last 7 lines say:

Running anaconda script /usr/bin/anaconda
unsing only installclass _Fedora
_Fedora is only installclass, using it
Display mode = t
Method = cdrom://hdc:/mnt/source
anaconda floppy device fd0
no /tmp/fcpconfig; not configuring zfcp

in tty4 last few lines:

looks like a raid problem...

with "linux nodmraid" its all ok...

Bouncing to anaconda since this appears to be unrelated to X.

Fedora Core 5 and Fedora Core 6 are, as we're sure you've noticed, no longer
test releases. We're cleaning up the bug database and making sure important bug
reports filed against these test releases don't get lost. It would be helpful if
you could test this issue with a released version of Fedora or with the latest
development / test release. Thanks for your help and for your patience.

[This is a bulk message for all open FC5/FC6 test release bugs. I'm adding
myself to the CC list for each bug, so I'll see any comments you make after this
and do my best to make sure every issue gets proper attention.]

If you're currently running a version of Fedora Core between 1 and 6,
please note that Fedora no longer maintains these releases. We strongly
encourage you to upgrade to a current Fedora release. In order to
refocus our efforts as a project we are flagging all of the open bugs
for releases which are no longer maintained and closing them.

If this bug is still open against Fedora Core 1 through 6, thirty days
from now, it will be closed 'WONTFIX'. If you can reporduce this bug in
the latest Fedora version, please change to the respective version. If
you are unable to do this, please add a comment to this bug requesting
the change.

Thanks for your help, and we apologize again that we haven't handled

There is a bug where the dmraid stuff just blocks.  This bug has not been solved
yet and we are still working to fix it.   However there is a work around.  If
you use nodmraid, the installer will ignore/skip the dmraid stuff allowing the
install to finish.  This is a workaround and does not fix the problem.
There is a long list of bugs that are filed against this problem.  This bug is
one of them.  We have decided to close all the related nodmraid bugs and leave
just one open that will represent all of the others.  So this bug will be duped
for this reason.
