Since upgrading to 2.3.34 I noticed some warnings like
elfie:~ # tail -n2 /var/log/warn
Dec 21 20:24:23 elfie kernel: hdb: multwrite: count=2, current=0
Dec 21 20:24:53 elfie last message repeated 16 times
in the logs.
elfie:~ # hdparm -i /dev/hdb
/dev/hdb:

When I disable the blockmode with "hdparm -m0 /dev/hdb" the
warnings go away ....
