test3 responsible for atomic blast!

[Bob Gill <gillb4@telusplanet.net>]

The really good news is 2.6.0-test3 is *much* more efficient at
delivering error messages than earlier versions!  
The following is from /var/log/messages:

... the bad: scheduling while atomic!  keeps blasting away at my screen
until I shutdown.  I *do* shutdown right away before the system decides
to really hang (and take out my root partition on next startup like it
has done when I get these atomic crashes).  Long before any real testing
begins, nasty bugs like this have to go!
