No longer is the problem only observed on ampere2! But this was with
a non-debug, personally built kernel that has some of my now patches.
I'll see if I can replicate the issue with an official pkgbase debug
kernel.
FYI for the replication that I got:
/usr/local/sbin/pkg-static add -A /packages/All/graphviz-9.0.0_4.pkg
runs:
/usr/local/bin/dot -c
each such /usr/local/bin/dot is stuck at MWCHAN urdlck .
