Hello, linux-dvb! I recently purchased a VisionPlus VisionDTV SAT-CI card (which is some Twinhan clone) with a Conax CI (PCMCIA), and installed it on an AMD machine running a x86_64bit 2.6.11-gentoo-r11 kernel with necessary modules (see successful-dmesg snippet below). Then I successfully ran scan util to fetch a channels.conf. After that, I did a few szap's and got frequency lock as I should. However, after a few boots the dvb-bt8xx can suddenly, for no given reason, no longer load/find a frontend driver (see failure-dmesg snippet below), hence /dev/dvb/adapter0/frontend0 does no longer exist. No changes were made to the kernel, modules or configuration. A cold boot is not helpful and I have been stuck with this problem for two days now. Any hints on how I could debug this, or solve it, is highly appreciated. ---------successful------------------------------------- Linux video capture interface: v1.00 bttv: driver version 0.9.15 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0).
