Comment 1 Chris Lumens 2006-08-16 10:32:10 EDT
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:

> The Mksquashfs bug is a 'corner case bug' that occurs when the number
> of fragments in the filesystem is a multiple of 512 bytes.  Your
> 'rawhide' builds may be hitting this magic number every couple of days
> causing the intermittent bug.
> There is only one way to check this which is to analyse the Squashfs

> Squashfs filesystem' or 'OK Squashfs filesystem'.

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

Comment 5 Chris Lumens 2006-08-17 10:33:26 EDT
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.
