Yes, please. Could you do (assuming your built kernel sources are in
/usr/src/linux-2.6.13-rc6):
cd /usr/src/linux-2.6.13-rc6/drivers/block
objdump -Sl ll_rw_blk.o | sed -e '0,/generic_make_request/d' |
sed -e '350,$d' | bzip2 -9 - > lrw.bz2
And then email me the file lrw.bz2? Thanks!
Without the disassembly it is difficult to find out which source code line
exacatly triggers this oops...
