What is .WITH. the Debian amd64 kernel and SpeakUP?

[Kirk Reiser]

There seems to be a bug in speakup running on quad core processors
which produces garbled speech output occasionally.  I have not been
able to nailed down an exact situation which will consistantly produce
the effect but it happens regularly.  There must be some lock which is
not set and therefore the text gets into the output buffer in a
disordered fashion.  Reviewing the screen will of course read it
correctly.
