[I messed up the freebsd-emulation email address the first time I sent
this. I also forgot to indicate the qemu-user-static vintage relationship.]
I had been reporting intermittent hang-ups for my amd64->{aarch64,armv7} port
cross
builds in another message sequence. But it turns out that one thing I ran into
has hung-up every time, the same way, for amd64->armv7 cross builds:
multimedia/gstreamer1-qt@qt5 . So I extract the material here into a separate
report
with some updated notes.
A little context: I had built from ports head -r484783 before under FreeBSD head
-r340287 (as I remember the version). Back then it did not have this problem
that it
now has under FreeBSD head -r341836 . One ports-specific change was to force
perl5.28
as the default instead of perl5.26 originally. In fact this is what drives what
is
being rebuilt for my experiment that caught this. But I doubt the perl version
is
important to the problem. The context has a Ryzen Threadripper 1950X and has
been
tested both for FreeBSD under Hyper-V and for the same media native-booted. Both
hang-up at the same point as seen via ps or top. The native tools for
cross-build
speedup were in use. Cross-builds targeting aarch64 did not get this problem but
targeting armv7 did. 121 of 129 armv7 ports built before the hang-up for the
first
armv7 try.
ADDED: The qemu-user-static back with head -r340287 before installing the
updated ports would likely be different than the -r484783 vintage. So both
FreeBSD and qemu-user-static may have changed over the comparison.
The hang-up:
In the port rebuilds targeting armv7, multimedia/gstreamer1-qt@qt5 hung-up and
timed
out. Looking during the wait in later tries shows something much like (from one
of the
examples):

So: waiting in kqread trying to run cmake.
Unlike some intermittent hang-ups, attaching-then-detaching via gdb does not
resume the hung-up processes. Kills of the processes waiting on kqread stop
the build.
Given the prior ports have been built already, building just
multimedia/gstreamer1-qt@qt5 still gets the hang-up at the same point.
Building anything that requires multimedia/gstreamer1-qt@qt5 seems to be
solidly blocked in my environment.
