Java threads hang on x2200 AMD/Solaris 10

Hi all,
I've got the following problems:
1) The result of System.nanoTime() on Solaris/AMD64 returns unexpectedly huge value and then doesn't increase: http://forums.java.net/jive/thread.jspa?threadID=61998
2) During an execution of java.util.concurrent.locks.Condition.await(timeout, TimeUnit.MILLISECONDS) a thread hangs on Solaris/AMD x64 instead of being resumed after timeout is gone: http://forums.java.net/jive/thread.jspa?messageID=341135

The first problem causes the second one. So we can speak about one problem with nanoTime on AMD/Solaris.

The environment is:
java version "1.6.0_14" (in the attached posts java version is 1.6.0_13, but I've just run the tests again on 1.6.0_14 - the problem is still reproduced)
SunOS x2001 5.10 Generic_137138-09 i86pc i386 i86pc
x2200 M2, AMD Opteron 2356 2 CPU x Quad-Core 2312 MHz, 16 GB RAM

If you have available AMD dual or quad core CPU (for example from the list http://www.sun.com/x64/products_amd.jsp), could you please run the Java test attached to the first post http://forums.java.net/jive/thread.jspa?threadID=61998 ? I just want to figure out if this problem is global or there is something wrong with my x2200 or Solaris 10.
