Okay. Built a FC2 SMP kernel without CONFIG_REGPARM, and rebuilt OpenAFS
against it. And still, Oops. This is 2004-06-17 snapshot, plus Rainer's
four patches, plus the tiny one to fix the vermagic. I didn't try either
of your later patches to fix that, because I'm a bit confused. :) What else
should I do at this point? Thanks!
