System stops after issuing warning and message to copy and file report 
with bugzilla

message too long to repeat but goes like this:-

File "/var/tmp/anaconda- 7.0.1//usr/lib/anaconda/iw/progress_gui.py"line 
20,in run
rc=self.todo.doInstall O
File "/var/tmp/anaconda-7.0.1//usr/lib/anaconda/todo.py"line 1472 in 
doInstall
self.fstab.mount Filesystems ( self.instPath)

ends with - raise SystemError, (errno,msg)
SystemError:( 22,'invalid argument')

it then shuts down and reeboots
