I'm seeing the same issue as well. I thought that maybe some recent Si2168 changes did impact this, but it does not seem to be the case. I made a quick test myself. I reverted the latest si2168 patches one by one, but that did not remedy the situation. Anyway, the kernel log does not seem to indicate that the si2168_cmd_execute itself would fail (which is what happens after the I2C error handling patch in case the demod sets the error bit). olli@dl160:~/src/media_tree/drivers/media/dvb-frontends$ git log --oneline si2168.c d4b3830 Revert "[media] si2168: add support for gapped clock" eb62eb1 Revert "[media] si2168: add I2C error handling" 7adf99d [media] si2168: add I2C error handling 8117a31 [media] si2168: add support for gapped clock 17d4d6a [media] si2168: add support for 1.7MHz bandwidth 683e98b [media] si2168: return error if set_frontend is called with invalid para c32b281 [media] si2168: change firmware variable name and type 9b7839c [media] si2168: print chip version dmesg lines when it fails (this is with a card that has worked before): [66661.336898] saa7164[0]: registered device video0 [mpeg] [66661.567295] saa7164[0]: registered device video1 [mpeg] [66661.778660] saa7164[0]: registered device vbi0 [vbi] [66661.778817] saa7164[0]: registered device vbi1 [vbi] [66675.175508] si2168:si2168_init: si2168 2-0064: [66675.187299] si2168:si2168_cmd_execute: si2168 2-0064: cmd execution took 6 ms [66675.194105] si2168:si2168_cmd_execute: si2168 2-0064: cmd execution took 2 ms [OLLI: The result of this I2C cmd must be bogus] [66675.194110] si2168 2-0064: unknown chip version Si2168- [66675.200244] si2168:si2168_init: si2168 2-0064: failed=-22 [66675.213020] si2157 0-0060: found a 'Silicon Labs Si2157-A30' [66675.242856] si2157 0-0060: firmware version: 3.0.5 Cheers, -olli On 3 June 2015 at 10:02, Antti Palosaari <crope@xxxxxx> wrote: > On 06/03/2015 10:55 AM, Antti Palosaari wrote: >> >> On 06/03/2015 06:55 AM, Stephen Allan wrote: >>> >>> I am aware that there is some development going on for the saa7164 >>> driver to support the Hauppauge WinTV-HVR2205.
