Unfortunately I got the same errors. This time the ranges are
different, of course.

master:

N2350 > bootflow scan scsi
CACHE: Misaligned operation at range [3fb99f88, 3fb9a388]
CACHE: Misaligned operation at range [3fb99f88, 3fb9a388]
CACHE: Misaligned operation at range [3fb99f88, 3fb9a388]
ERROR: v7_outer_cache_inval_range - start address is not aligned - 0x3fb99f88
ERROR: v7_outer_cache_inval_range - stop address is not aligned - 0x3fb9a388

next:

N2350 > bootflow scan scsi
CACHE: Misaligned operation at range [3fb80388, 3fb80788]
CACHE: Misaligned operation at range [3fb80388, 3fb80788]
CACHE: Misaligned operation at range [3fb80388, 3fb80788]
ERROR: v7_outer_cache_inval_range - start address is not aligned - 0x3fb80388

Thanks,
Tony
