Without evidence it sounds like the user may be running out of CPU budget
rather than any particular bug. I agree with Kristof that we need more
information and the vendor/project needs to help qualify what and where issues
are first or this will fatigue devs if it turn into a raw support forum for
issues like that.
If there is an obvious FreeBSD defect (for instance a panic in unmodified code)
I'd send it here right away. Otherwise I think you should figure out how to
help users produce more qualified reports, a debug bundle including things like
dmesg, pciconf -lv, relevant sysctls (to include stats ones for the NIC),
netstat etc is the standard Mellanox wants when I interact with them in my
dayjob, maybe worth consideration here. In this case I'd suggest a more direct
approach of some 'top' output while bw limited, and even better some pmcstat
for at least instructions retired https://wiki.freebsd.org/PmcTools/PmcTop.
