I got some HANDSHAKE_REG messages, but they are not a problem because the output of my card is ok. But after the av7110_fw_cmd error -110 the output of my card was damaged. I saw a fixed image. I have two (nexus rev2.3) cards in my system and only one card has a problem. The output of the second card is still ok after the error occured. Any suggestions logfile: Jun 10 03:54:39 e kernel: av7110_fw_request: timeout waiting for HANDSHAKE_REG Jun 10 03:54:39 e kernel: dvb-ttpci: StopHWFilter error cmd 0b08 0001 0008 ret ffffffff resp 75a0 c16d pid 320 Jun 10 03:54:46 e kernel: av7110_fw_request: timeout waiting for COMMAND to complete Jun 10 03:54:46 e kernel: dvb-ttpci: StopHWFilter error cmd 0b08 0001 0006 ret ffffffff resp 2000 002c pid 16 Jun 10 10:04:48 e kernel: dvb-ttpci: __av7110_send_fw_cmd(): timeout waiting for COMMAND idle Jun 10 10:04:48 e kernel: dvb-ttpci: av7110_send_fw_cmd(): av7110_send_fw_cmd error -110 Jun 10 10:04:48 e kernel: dvb-ttpci: av7110_fw_cmd error -110 ----------------------------------------------------------------
