Hi, I think I am experiencing the same symptoms using 2.6.23.9-rt12 on a Core 2 T7400 running 32 bits Linux (National Instrument PXI 8106 controller). The .config used is the untouched default configuration as provided in the 2.6.23.9-rt12 kernel sources. Has there been any solution/workaround found on this subject since the last message in this thread?
