Hello,
I'm attempting to get a brand new HVR-1600 working on CentOS 5.2
(2.6.18-92.1.22.el5.centos.plus kernel). System is Dell PowerEdge 2500SC
with dual PIII CPUs. Prior to purchasing this card I profusely read all the
issues folks were having on this list and others with the cx18 driver and
decided to risk it, verse going with a PVR-500/350 + separate HDTV card, and
so here I am. I'm reasonably proficient with Linux but not a sw programmer.
My current setup is a split MythTV backend/frontend with the backend on the
PE2500, frontend's running Minimyth. I have a AverMedia (Bt878 based)
capture card working reliably with NTSC from my cable provider (Coax in) on
the PE2500 backend. Here's what I've done to date to try and get this to
work and debug the issue.
- Grabbed the latest V4L distribution (v4l-dvb-94592e006b95) and compiled as
per instructions and installed. Had some initial compile issues, directories
not found etc which I've fixed.
- Downloaded the HVR firmware to /lib/firmware which seems to load
correctly.
- Following a reboot everything with respect to the cx18 driver seems to
load fine, I have some debug captures of this here;

With more debugging turned on;
http://thinkspace.ath.cx/stuff/hvr-1600_debug2.txt
The bttv driver (/dev/video0) and associated modules for that are loaded
prior to the cx18 module which becomes /dev/video1
- The issues is after everything seemly going fine, I get no signal from the
/dev/video1. Testing via xawtv, mplayer and mythtv all reveal a blank red or
green screen. Almost as if the input on the HVR-1600 is set to composite 1
or 2 but it not as far as I can tell!
- Switching the coax cable to connect to the ATSC, I'm able to tune in
successfully to some QAM-256 channels, so the driver is working to some
degree. Here some photos of the card, it's the MCE version with the built in
FM tuner.

- After having read of the I2C bus issues I placed the card in a 3.3V 64bit
PCI slot that should be PCI 2.3 compliant. The PE2500 has both 5V and 3.3V
64bit PCI slots. Have some hardware details here, card seems to be detected
fine.

- After having read here that for the PVR-500 sometimes the bttv drivers
causes tuner detection to not work (Tuner not detected), and since the cx18
is based on this code, I tried blacklisting the bttv and snd_bt87x drivers
at startup, and this did end up giving me an error during cx18 load.

- Here is the current cx18 dmesg error with debug=32,
http://thinkspace.ath.cx/stuff/hvr-1600_debug3.txt
- Also modprobe -r of the cx18 module at any points ends up with a kernel
soft lockup as below which is only recoverable via a reboot.

Was there some problem with the build process perhaps?
I'm kind of running out of ideas on what else I can do to further diagnose
this issue, any help or pointers would be greatly appreciated.
Many thanks,
Tony
