# e2e run on kernel #1 (mask only, DF-2915 unfixed) - "DragonFly 6.5-DEVELOPMENT #1: Thu Sep 3 09:02:18 UTC 2026"
# command: kldload /root/sqe2e.ko

# The ssh session DIED during kldload because the kernel panicked; nothing
# could be returned over the connection. The full console evidence was
# captured from the QEMU serial log (boot.log) and is preserved verbatim
# in panic.txt:
