No, big deal. This particular problem (PCI mmio access errors to the CX23418) has dogged me for a few months. I thought I had it fixed for good with driver version 1.0.1.

Let's forget the big list of things to do. Your vmalloc allocations looked fine, so let's do this: 1. Blacklist the cx18 driver if you can, so that it doesn't automatically load on boot. (On Fedora it means adding an entry in /etc/modporbe.d/blacklist.) 2. Reboot and execute the following commands: $ sudo modprobe -r cx18 $ sudo modprobe cx18 debug=67 retry_mmio=1 enc_mpg_buffers=1 enc_ts_buffers=0 enc_vbi_buffers=0 enc_yuv_buffers=0 enc_pcm_buffers=0 3a. If the driver appears to load OK do this $ v4l2-ctl -d /dev/video0 --log-status 3b. If it does not load OK, do this $ sudo modprobe -r cx18 4. Send all output cx18 related out logged to dmesg (or /var/log/messages) Regards, Andy _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
