Bug#536354: linux-2.6: [s390,lenny] kernel panic during boot

[Frans Pop <elendil@planet.nl>]

Note that an additional issue was found with 2.6.27 after the change to
-fno-strict-overflow. See http://lkml.org/lkml/2009/7/20/80 and follow-ups 
for details.

The cause (compiler bug in gcc-4.2.4) was identified in 
http://lkml.org/lkml/2009/7/21/423 and it looks like it's going to be
"fixed" with a kernel patch: http://lkml.org/lkml/2009/7/21/499.

But it shows that there may definitely be unexpected effects from the 
change for arches using gcc-4.2 or later in Lenny.

Cheers,
FJP
