And thx to you for your help and time.

These are newly introduced so I didn't probe deeply. strace showed wait() time out

statx(1, "", AT_STATX_SYNC_AS_STAT|AT_EMPTY_PATH, STATX_BASIC_STATS,
{stx_mask=STATX_BASIC_STATS, stx_attrib0
kill(-1805, SIGKILL)                    = 0
kill(1805, SIGKILL)                     = 0
wait4(1805, [{WIFSIGNALED(s) && WTERMSIG(s) == SIGKILL}], WNOHANG|WSTOPPED, NULL)
= 1805
--- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_KILLED, si_pid=1805, si_uid=0,
si_status=SIGKILL, si_utime=0, si_-
write(1, "Timed out: killed the child proc"..., 35Timed out: killed the child
process) = 35
write(1, "\n", 1
)                       = 1

Very likely so.

Actually these are all OK. cross setup sometimes has issues (e.g. nfs automount at
boot not working) these tests hit first and fail. When testing is resumed the
failures stick. I have a clean list of current failure with v7.1 at the end of
this msg.

Indeed.

current list of failures:
Currently debugging the math errors, they are regression from recent rework for
reviews.
