The command that causes the panic is:

# duplicity / rsync://backuphost:873/kutelo1

It generally traverses the whole FS. When 500-600M are uploaded to
backuphost, the machine (the one that runs duplicity command) panics.

Below I have attached "uname -a" and "ident /boot/kernel/kernel"
commands output, the kernel config file, dmesg output and backtraces
with WITNESS_COUNT set to 200 (default) and 20000.

Note that I get different panic 'reasons' with WITNESS_COUNT=200 vs.
WITNESS_COUNT=20000.

Should I submit a PR (without a fix :/)?

Ready to go. Enter 'tr' to connect to the remote target
with /dev/cuaa0, 'tr /dev/cuaa1' to connect to a different port
or 'trf portno' to connect to the remote target with the firewire
interface. portno defaults to 5556.

Type 'getsyms' after connection to load kld symbols.

If you're debugging a local system, you can use 'kldsyms' instead
to load the kld symbols. That's a less obnoxious interface.

Ready to go. Enter 'tr' to connect to the remote target
with /dev/cuaa0, 'tr /dev/cuaa1' to connect to a different port
or 'trf portno' to connect to the remote target with the firewire
interface. portno defaults to 5556.

Type 'getsyms' after connection to load kld symbols.

If you're debugging a local system, you can use 'kldsyms' instead
to load the kld symbols. That's a less obnoxious interface.
