Peraphs I'm having a different problem.
I wrote a kernel driver for the 2.6 linux kernel. It basically sits on an
interrupt and tries to wake a *thread* (and not the main thread).
What happens is that the thread seems not to be awaken and it stops forewer
on the read function. If I make the main process stop waiting for the
driver, everything works fine.
I'm wondering: haw can the driver wake up the thread inside the process
having it only a reference to the process ID?
Is it a drivers-writer task to list all the thread and to call the
wake_up_interruptible function against them? Or is it a glibc/pthread task?

NPLT support did not make it into glibc-2.3.2 for powerpc (32/64). A lot
of changes went into NPLT and glibc to support NPLT since glibc-2.3.2 for
NPLT is supported at cvs-head (AKA glibc-2.3.3) and in the RedHat
Enterprise Linux 3 release for both 32- and 64-bit powerpc.
