2.6.14-rt15 @x86_64UP: "sem_post: Invalid argument"

[Karsten Wiese]

I get loads of those messages since switching from rt12 to rt15.
no other known change.

They happen during startup and when I trigger
i.e. an ardour build like this:
	$ scons

a typical strace excerpt:
----
futex(0x5012a0, FUTEX_WAKE, 1)          = -1 EINVAL (Invalid argument)
write(2, "sem_post: Invalid argument\n", 27) = 27
----

Other futex() calls like
----
futex(0x3b384030c8, FUTEX_WAKE, 2147483647) = 0
----
succeed.
  
This happens on fc4.
Maybe caused by a recent change from a semaphore to completion?
