[linux-dvb] OOPS for a year now and nothing improved!

[Rene Bartsch <ml@bartschnet.de>]

Hi,

I'm running a Rev 1.3 DVB-S in an old ICL/Fujitsu-box.

For a year now, I have oops when I try to add a Satelco Standard PCI 
DVB-S (= TT budget S-DVB Data Rev 1.1, BSRU6).

I've reported that oops several times for several driver-versions on the 
list, but nothing happened.

Windoze drivers work fine, so the bug has to be inside the linux DVB-driver.

After I read a pointer-bug was solved one or two weeks ago I tried 
tonight's CVS (DVB-driver, not kernel-CVS).

But still the same oops and error 139 like one year ago!

See oops.log in attachment!

ksymoops 2.4.5 on i586 2.4.18-14vdrbox.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.18-14vdrbox/ (default)
     -m /boot/System.map-2.4.18-14vdrbox (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.

Error (expand_objects): cannot stat(/lib/ext3.o) for ext3
Error (expand_objects): cannot stat(/lib/jbd.o) for jbd
Warning (map_ksym_to_module): cannot match loaded module ext3 to a unique module object.  Trace may not be reliable.
