Hi,

I am not sure, if this is a reiserfs related issue, so I send this Oops 
report both to the kernel mailing list and to the reiserfs people
(kernel has been patched with reiserfs-3.6.18).

During ripping the last song from a cd (a long time song of 9.50 min)
I was wondering about the time consumption of this process.
After the cdda2wav process had been finished I found the following
oops:


---------------------- starts here ---------------------- 
ksymoops 2.3.5 on i686 2.4.0-test10.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test10/ (default)
     -m /usr/src/linux/System.map (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.

---------------------- ends here ---------------------- 

The oops should have been emitted by the BUG() in
void * kmalloc (size_t size, int flags) in linux/mm/slab.c.

cdda2wav (version 1.9) was called with the following options (I think this 
options are correct, but I am not really sure, because it was called by grip)

-D1,0,0 -x -H -t9 -O wav

the .wav-file has been written to the reiserfs partition (ide-disk,
without DMA).
The cdrom drive is a Ricoh MP9060A, up to now there never
occured any problems with that. The ide-scsi driver has not been
compiled as a module, it is tightly integrated into the kernel as
well as the generic scsi support (sg).

(Maybe I should mention that the kernel has been compiled with
gcc-2.95.2, but I think, it is not very important.)

For the sake of completeness I append my .config at the end of this mail
(all lines with "is not set" removed)
