Yep, the linker_unload and T5435_v are known (tracking #5435) and I'll be fixing them today. Edward Excerpts from Jan Stolarek's message of Mon Sep 16 08:28:05 -0700 2013:

I'm getting these validation failures today on HEAD (64 bit Linux):

OVERALL SUMMARY for test run started at Mon Sep 16 16:18:39 BST 2013 3793 total tests, which gave rise to 15020 test cases, of which 11569 were skipped

28 had missing libraries 3362 expected passes 58 expected failures

0 caused framework failures 1 unexpected passes 2 unexpected failures

Unexpected passes: rts linker_unload (normal)

Unexpected failures: perf/compiler T5837 [stat not good enough] (normal) rts T5435_v [bad stdout] (normal)

T5837 started to fail randomly after the AMP warnings patch, but the two RTS failures are new. Edward, T5435_v is something you've been working on recently - could you take a look? Here is some output that might be helpful:
