Additional info:

This is a Penguin Computing Altus 1300, an AMD64 2-processor system with 16GB
RAM & 2x120GB HD configured with FC5 and updated. I'm using this at Cisco for
server consolidation.

I changed grub.conf to run level 3, after seeing graphics boot hang.

I tried the console_sync trick, it didn't work. It consistently freezes at the
same point (see console messages above).

Is this still reproducible on the latest stable release+updates?  Thanks.
Comment 2 Kirk Franks 2007-03-16 11:29:30 EDT
I've moved on to FC6 and don't see the problem. However there was a different
installation problem we found; we can't install FC6 on a machine with over 4GB
of RAM. I've switched to a smaller (RAM) machine and have been able to continue.
Has anyone else seen this? Is there a workaround?

Comment 3 Stephen Tweedie 2007-03-16 11:37:30 EDT
Do you mean you can't install FC-6 at all, even using the non-xen kernel?
Comment 4 Red Hat Bugzilla 2007-07-24 21:31:48 EDT
change QA contact
Comment 5 Chris Lalancette 2008-02-26 18:10:03 EST
This report targets FC5, which is now end-of-life.

Please re-test against Fedora 7 or later, and if the issue persists, open a new bug.
