hald on sym(4) causes phase change log spam

[Matthias Andree]

Greetings,

on a FreeBSD 6.2-STABLE machine that contains, among others,
a Tekram DC-390U2W SCSI HBA (SYM53C895) and a Plextor PX-32TS SCSI CD-ROM,
I get these pairs of log entries when running hald (hal-0.5.8.20070403_2):

(pass0:sym0:0:2:0): phase change 2-3 16 at 3e86a768 resid=10.
(pass0:sym0:0:2:0): phase change 2-3 16 at 3e86a768 resid=6.

Are these caused by:

- a firmware bug in the CD-ROM drive?
- a bug in the sym(4) driver?
- a bug or missing feature in hald?

Thanks,
