In i830_display.c:i830_crtc_load_lut in the loop for (i = 0; i < 256; i++) { OUTREG(palreg + 4 * i, (intel_crtc->lut_r[i] << 16) | (intel_crtc->lut_g[i] << 8) | intel_crtc->lut_b[i]); } when i == 2 the system freezes. The last thing gdb shows me is: (gdb) step 1943 OUTREG(palreg + 4 * i, 4: intel_crtc->lut_b[i] = 57 '9' 3: intel_crtc->lut_g[i] = 0 '\0' 2: intel_crtc->lut_r[i] = 63 '?' 1: i = 2 (gdb) step Any ideas? -stacy
