Comment 1 Chris Lumens 2006-08-16 14:32:10 UTC 
This appears to be a bug in making squashfs filesystems, as the machine is
locking when anaconda goes to mount stage2.img.

According to Phillip Lougher:

I have run his test program against our stage2.img and it does in fact show that
the image is bad.

Applied the patch from the upstream squashfs archives and built squashfs-tools-3.0-2

Comment 5 Chris Lumens 2006-08-17 14:33:26 UTC 
Today's rawhide works for me.  However just for future reference, I am attaching
a slightly different version of the mksquashfs patch as provided to me by
Phillip.  Please check and make sure whether or not we need the differences in
what went into 3.0-2.
