63 FAILs seems a bit high. For comparison these are my results on the
same setup (assuming x86_64, but i686 on f15 is similar, and even on
x86_64/rhel5 I don't get more than 30 FAILs - admittedly I did clean up
the testsuite in the last week, so if your run is from a couple of days
ago then you might want to rerun):

# of untested testcases         62
# of unsupported tests          2

Do you know where those extra 40 FAILs come from?
Below is my FAIL list. 13 come from the nd_syscall testcase, which
probably should be marked KFAIL (or is that XFAIL).

Cheers,

Mark
