My pattern was cyclical every 256 bytes, so it missed a fairly obvious

we never generate identical sector patterns.

As of the introduction of this test the test suite fails on FreeBSD,
with 6 errors of the form:
ERROR:tests/ahci-test.c:790:ahci_test_io_rw_simple: assertion failed
(memcmp(tx, rx, bufsize) == 0): (0xffffffffffffffff == 0x00000000)
GTester: last random seed: R02S76f68c4cfb2d54af66de227ed44fd54a
I haven't yet done any investigation beyond bisecting.
which test case does it fail under? io_rw_simple is shared by a number
of different tests.
I suspect deeply that this test pattern has just unearthed an existing
problem.
