I have not had much luck reproducing your results today despite
reporting the same parameters in the VPD pages as your device.

I would appreciate if you send me the output of:

# grep . /sys/block/{sd,dm}*/queue/write_zeroes_max_bytes /sys/block/sd*/device/scsi_disk/*/max_write_same_blocks

for the failing configuration.

Thanks!
