as do the nosmp sparc32 boot tests, but sparc32 boot tests with SMP enabled still fail with lots of messages such as:

Code path leading to that message is different but always the same from free_unref_page().
Still testing ppc images.
ppc image tests are passing with this patch.
How about sparc? I finally got your scripts to run on sparc and everything looks to be passing?
Are we all good now?
Thanks again! Ira
