Is it likely that the digital output (node > 0x14) is causing problems (it's not wired to anything)? I've manually crippled the code that enables the digital output (commented out the following lines in patch_via.c at line 846 ish): if (spec->autocfg.dig_out_pin) spec->multiout.dig_out_nid = VT1708_DIGOUT_NID; if (spec->autocfg.dig_in_pin) spec->dig_in_nid = VT1708_DIGIN_NID; This hasn't helped, beyond removing the last_cmd message from dmesg. Back to the drawing board for me. -- Simon Farnsworth
