Hi,
I am attaching an oops report which I get with 2.4.0-test9 when I
echo scsi dump 0 > /proc/scsi/scsi
The system is an Intel Pentium II laptop with scsi emaulation built
into the kernel.
Unfortunately, I could not really get anywhere with ksymoops so any
pointers to its proper usage would also be appreciated.
Thanks,
Richard
echo "scsi dump 0" > /proc/scsi/scsi gives an oops. ksymoops does not really help all
that much 8-(
Here is the oops:

and here is the output from ksymoops. Perhaps someone can point out what I doing wrong
with it
so that I can get more useful output.
