for the record i am running 2.6.7-rc2 on a 2-proc SMP system but
i dont use CONFIG_REGPARM.  it seems pretty likely that this
is part of your problem.  you might need to make sure the your
libafs is being built with the same gcc as the kernel (this 
should be fixed with the new build scheme from jeff).

osi_Init() should probably do the following to create
the anonymous cred instead of inheriting current. comments?
