Interesting. It looks like the 3ware handles this at the driver level
instead of passing the command through to the disk and letting it
fail. That in turn means that the logic we have in place to disable WS
when the disk does not support it does not get triggered.
The driver should really fill out the sense buffer in that case.
Could you please test the patch below?

The second question is what it is that's issuing these zeroouts at boot?
Which filesystem are you using? What's your DM/MD config?

3w-xxxx: Create sense buffer for unsupported commands
Make the driver return appropriate sense data when an unsupported
operation is queued. This will cause the SCSI layer to stop issuing the
offending command.
