Bug Description
Binary package hint: rsyslog
rsyslog (4.2.0-2ubuntu5) karmic; urgency=low
* debian/
messages.
With the default value of 512, dd would wait for the buffer of such size
to become full before calling write(), potentially delaying some kernel
messages for a very long time.
debdiff attached.

Thank you for the report and patch! This is a regression, and the fix (restoring bs=1) is part of a patch in bug 430220. I'm going to mark as a dup.
