/etc/init.d/klogd stop
echo 1 >/proc/sys/vm/block_dump
/sbin/klogd -n -f -

watch lots of spew

^C
echo 0 >/proc/sys/vm/block_dump
/etc/init.d/klogd start

that will tell you a lot of stuff.  it will probably lead you to a process 
or two as culprits... use strace(8) to attach to those and get more 
specific information.

now... share with me how to do this on windoze?  :)  i'm trying to get rid 
of the last write or two on my laptop...
