See > test "set probe hw watchpoint" in watchpoint-stops-at-right-insn.exp. > Agreed, ppc64[le] gdbserver currently does not implement hw watchpoint support; however, despite the high number of failures on the mentioned test (and possibly others) because of that, from what I could git-bisect, it didn't hang the native-gdbserver testrun until commit c65d6b55b3a592906c470c566f57ad8ceacc1605.
