I did some debugging with 'ir_debug=1 i2c_debug=1 irq_debug=1 gpio_tracking=1' for saa7134 and 'debug=1' on both ir_common and ir_kbd_i2c and when i do this the remote seem to be working fine. I have logfiles at http://www.linuxguru.se/temp/messages.gz and http://www.linuxguru.se/temp/syslog.gz if anyone is interrested in looking at it. // Jimmy _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
