Comment 1 RHEL Product and Program Management 2007-05-07 14:46:06 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.
Comment 2 Bhavna Sarathy 2007-05-07 18:21:22 UTC 
With "rhgb" removed in grub, the system completes "checking for new hardware"
successfully, but hangs at smartd (daemon that monitors hard drives).  This
could be an X.org issue.
Comment 3 Adam Jackson 2007-05-07 20:18:53 UTC 
I don't think this is an X issue.  Turning off smartd and cpuspeed with
chkconfig makes the box boot reliably.  With either one enabled I can't get the
machine as far as runlevel 3 (ie, no rhgb, no X at all).  There's nothing in the
X log characteristic of the usual failures we see on large machines.

So I think this one's not my fault, at least not yet.
Comment 4 Bhavna Sarathy 2007-05-17 15:35:00 UTC 
AMD has successfully installed and booted RHEL4.5 on a 4p/16c GH B0 system.
