I'm not sure off hand how to run an individual test to confirm, but the testrun output up to the failure is: LINK tests/spapr-phb-test GTESTER check-qtest-aarch64 GTESTER check-qtest-alpha GTESTER check-qtest-arm GTESTER check-qtest-cris GTESTER check-qtest-i386 blkdebug: Suspended request 'A' blkdebug: Resuming request 'A' ** ERROR:tests/ahci-test.c:790:ahci_test_io_rw_simple: assertion failed (memcmp(tx, rx, bufsize) == 0): (0xffffffffffffffff == 0x00000000) GTester: last random seed: R02S181acd6574060796874e02dbdeb86199 Generally speaking I've only encountered build errors on FreeBSD, and as long as it built the full test suite passed. > I suspect deeply that this test pattern has just unearthed an existing > problem. Yeah, it's almost certainly just exposing the existing failure.
