[K12OSN] K12LTSP 7.0 crash on install

[informatik at steinerschule-basel.ch]

Had the same problem on proliant ml570 4GB RAM, cciss raid disks:
crash after formatting the hard drive (working fine with k12ltsp 6)

Anaconda backtrace showed exception in change_loop_fd which changes the 
install image from cd 1 to a harddisk copy (to allow insertion of cd 
2,3 ..).

I had repeatedly the same behavour, with rc4-Version and with testing 
version from june 1st.

Workaround: copy images to a spare ext2 formatted hardisk partition 
(e.g. boot with cd 1 in rescue mode, create and cd into directory /iso 
on this partition and use dd to copy the cds, or use wget to download 
them directly: 1.iso, 2.iso, ...).

Then reboot with cd 1 and use tab-key to edit the grub bootloader line 
for entry "install": add to the kernel command line:
method=hd://cciss/c0d1p1:/iso
(replace cciss/c0d1p1 by the device of your partition with the iso images)

Now, in my case, the installer worked
... to show bugs with the installed system (soft lockup cpu 0..., freezes)
