bug-no. 179075 and 179080

addional info's
it has to read:
starting udev: "Unable to handle NULL pointer dereference at 0000000000000014fc"
and 
...
PGD 1e859067 PUD 1e859067 PMD 0

can you capture the full information (the bits where you put ... are actually
important).  Even a digital camera photo attachment would be ok if you have one.
(Also use vga=791 or vga=1 to fit more lines of text onscreen)

no I can't, now.
I tried to do a fresh installation with boot.iso/rescue.iso from today's iso's
to get rid of this bug, but the installation was aborted with that iso's.
I try to do new one tomorrow, may be tonight, when new iso's on the mirrors.
if the bug is still there I make a digital photo.
Okay ?
