I'm still not having any luck getting reliable operation of the second tuner on my cx23885 based card. Incidental to this, I'm getting a crash in cx23885_video_wakeup at the line: buf->vb.v4l2_buf.sequence = q->count++; (full log follows this email) I'm not sure exactly why, but I do know that the hardware is well and truly messed up at this point. IRQ's are reading 0xffffffff from a lot of the hardware registers etc. Is it worth putting a test in cx23885_video_wakeup to stop it following bad pointers and recovering from a potential crash, or are things so bad by this point that it isn't worth it? I'm getting things like this too: Uhhuh. NMI received for unknown reason 21 on CPU 0. Do you have a strange power saving mode enabled? Dazed and confused, but trying to continue Everything works perfectly with only one tuner enabled so I still think the hardware is okay.
