I don't think so. The example said

"Strange, kseriod not stopped"

This names a process that admittedly took a long time to stop, but not
the real *cause* of the failure. There was nothing wrong with kseriod.

FWIW, debugging this was way out of my league. I might have had a
better chance if it mentioned a short, fixed timeout. I also noticed
that it wasn't very obvious to you either at first. The first thought
was a failing serio driver, although that admittedly might be because
I mislead you in my attempt to pinpoint the failure.

But my first post in this thread *did* include the printk() you
mention above, so it should have been possible to debug it quickly...
