Yep, the kernel as of date=2006.06.27.18.28.00 works fine
and of date=2006.06.27.18.33.00 is broken. Thare are a couple of jhb's
patches for linux rpc calls. However, none of those calls are used when
a programm is failing. Hence the following Alexander's proposal to
concentrate on linux tests seems right.
