[linux-dvb] OOPS in dvb_demux_release

[Christian Schuld <chris@sonnengesicht.de>]

Hi,

yesterday I tried the CVS version of dvb-kernel and got following OOPS while 
exiting VDR and reload the driver.
I have two rev 1.3 dvb-s and one nova dvb-s.

ksymoops 2.4.9 on i686 2.4.25.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.25/ (default)
     -m /boot/System.map-2.4.25 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Warning (expand_objects): 
object /lib/modules/2.4.25/kernel/fs/reiserfs/reiserfs.o for module reiserfs 
has changed since load
