I suggest that you give the exact kernel version, as a courtesy to those
not running kubuntu 9.10.

You can use "dmesg -c" to erase the kernel log.

Getting kernel log from /var/log is not a good idea.  Please use the
dmesg command.

You can use less debug options to get something of manageable size.  You
can use sed to remove the timestamps (I don't think they are very useful
for this particular problem) and use lzma to compress the log:

dmesg | sed 's/^[^]]*] //' | lzma >kernel.log.lzma
