Raphael?!?! How many times did I post the necessary patch for that???
;-))))))))

I don't know exactely in which release it was included, but your kernel
does not exists, 2.6.32.2 is not existing, we are still in the 2.6.32-rc
series.

There is a simple patch that has been included in some distribution 
kernels, but not in an unpatched kernel. Now it is included, and since
that patch I never had any problems (and I had *many* problems before).

I attach the patch again, you might put it up somewhere for those using
older kernel.

Best wishes

Norbert
