May be this is a good point. But I don't dig with it, just stop to use new kernels temporarily and still using 2.6.31-rt One more significant(for me) reason for still using 2.6.31, except nvidia-problem, is that I find out that command ps output was somehow changed in subsequent kernels, so steps starts from 3 from http://subversion.ffado.org/wiki/IrqPriorities is not working. -- Truly yours, Oleg Ivanenko aka Ash [if it wasn't so sad, it would be funny]
