Poul, thanks for the sharing. Now my R400 is usable again !!! :) BTW, I'm not sure if this drm is the root cause, since one of my tricks to get the "unusable" laptop back to work is to switch off the wlan/unplug the USB mouse etc. As I reported earlier, the interrupts from graphic/ethernet and other peripherals are extremely high when my R400 is not usable. I'm wondering why these two symptoms are correlated.
