I'm having the same problem with an i686 Rawhide virtual machine
(using KVM, on a Fedora 15 x86_64 host).  The last few lines I see
before the hang are these:

Started udev Kernel Device Manager.
Starting Stdio Syslog Bridge...
Started Stdio Syslog Bridge.
Started udev Coldplug all Devices.
Starting udev Wait for Complete Device Initialization...
[    9.542951] EXT4-fs (dm-1): re-mounted. Opts: (null)
Started Remount API VFS.
Started Remount Root FS.
Started Apply Kernel Variables.
Starting File System Quota Check...
Starting Configure read-only root support...

At that point output stops for awhile.  The "CPU usage" graph on
virt-manager jumps up to about 25% to 30% (eyeballing it), and the
"Disk I/O" graph drops to zero.  If I leave it like that for awhile to
see if anything else will happen, I eventually start seeing messages
about CPU stalls.

Just in case it is relevant, earlier in the boot, I see this:
