>Description:
I am using an HP scanner with FreeBSD on a SMP kernel. As of the
3.0-971225-SNAP release the ptN driver seemed to work very well.
With the modification within the past two weeks, ptN no longer
works.  Instead, zero bytes are read from the scanner and a kernel
error message:
     pt0: physio split the request.. cannot proceed.
is issued. I reverted to the kernel from the 971225 SNAP and pt seems
to behave properly.  I can read the scanner without a problem.
>How-To-Repeat:
Use any kernel built after ~980110.
