Comment 1 Jeroen Roovers (RETIRED) gentoo-dev 2008-10-02 16:29:32 UTC
It's probably a good idea to attach the dmesg output, the kernel config, and the output of lsmod.

The point is; there is no output specifically to this module... and use stays 0.
Comment 3 Mike Pagano gentoo-dev 2008-10-03 13:14:56 UTC
Can you please test with the latest git-sources (at least equal to or greater than git-sources-2.6.27_rc8-r5).

Tested with the git sources, same issue.

This is the output *after* I type modprobe -r saa7134_dvb:

Comment 5 Stefan de Konink 2008-10-19 17:08:12 UTC
Still the same problem for latest .27. Can this be reported upstream?
Comment 6 Mike Pagano gentoo-dev 2008-10-19 19:20:36 UTC
Yes, please post to http://bugzilla.kernel.org and add the bug url into the URL field on this bug.

Comment 7 Stefan de Konink 2008-10-19 19:29:31 UTC
Don't know if it will be picked up there. But asking in an existing report is probably better.
Comment 8 Mike Pagano gentoo-dev 2008-10-28 19:04:35 UTC
I see no one has addressed your issue in the upstream bug. Still an issue with 2.6.27 or dev kernel >=2.6.28_rc2-r2 ?

I'm typically not a user of git kernels, I don't know.
Comment 10 Mike Pagano gentoo-dev 2008-10-28 19:43:16 UTC
ok,then. We'll follow the upstream bug.
