Question is what to do about the messages. I can think of a few options:
1. move them to verbose mode. There are more drivers that spew this kind of
message in verbose mode.
2. handle them trough the quirk mechanism. I was told that this would cause
kernel-bloat but that might be remedied by using a more compact format (now
17 bytes per entry) for the quirk table and/or allowing the quirk table to
be paged out (if possible?)
3. issue them only when the driver expects it to be a quirk. There are a lot
of drives that will cause the openings to run down to a certain number and
stay there. Don't issue a warning when the number stays above ??.
4. adjust the number of tagged openings on boot. Simply issue a lot of
tagged openings and adjust the number appropriately. This would look very
nice:
da0 at ahc0 bus 0 target 0 lun 0
da0: <CONNER CFP4207S 4.28GB 1524> Fixed Direct Access SCSI-2 device
da0: 5.0MB/s transfers (5.0MHz, offset 15), Tagged Queueing Enabled (31
concurrent transactions)
da0: 4096MB (8388608 512 byte sectors: 255H 63S/T 522C)
or, if you want to do something about the formatting of the boot msgs:
da0 at ahc0 bus 0 target 0 lun 0
<CONNER CFP4207S 4.28GB 1524> Fixed Direct Access SCSI-2 device
5.0MB/s transfers (5.0MHz, offset 15), Tagged Queueing Enabled (31
concurrent transactions)
4096MB (8388608 512 byte sectors: 255H 63S/T 522C)
A combination of these ideas might do. Basically you want to get rid of the
warnings when there's nothing wrong with the hardware.
DISCLAIMER: I don't know much about CAM so please don't shoot me if this is
nonsense...
Cheers,
Jeroen
