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?
Karsten

fixed in rt20.
I've got an "io_apic cached" patch for x86_64 here,
that ticks since weeks on my UP. Interisting?
danke,
Karsten
