Re: dvb-s2 card "TeVii S472" (cx23885)

[Hendrik Oenings <debian@oenings.de>]

Hi Olli,

I've tested the driver, it compiles well and I've installed it on my
system.
But there's a problem: Everytime I try to load the driver (exact: the
module cx23885), modprobe (or insmod) is giving me the following:
# modprobe cx23885
modprobe: ERROR: could not insert 'cx23885': Exec format error

I've also tried to compile it with the current 4.6er kernel, but it
stays the same.
$ uname -r
4.6.0-rc5

I've also tried to recompile the driver, but it didn't help.

Maybe it is important to mention that some patches fail at the
beginning of the build process (pr_fmt, debug).

The installed module seems to be correct file format (my arch is
x86_64):
$ file \
 /lib/modules/4.6.0-rc5/kernel/drivers/media/pci/cx23885/cx23885.ko

/lib/modules/4.6.0-rc5/kernel/drivers/media/pci/cx23885/cx23885.ko: ELF
64-bit LSB relocatable, x86-64, version 1 (SYSV),
BuildID[sha1]=07a3f2f2fe383ab691b0022568dcd4d8315dc4b8, not stripped

Regards,
Hendrik
