[linux-dvb] dvb-bt8xx: A frontend driver was not found for device 109e/0878 subsystem 1822/0001

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.
