I come back with a little more informations.
It seems that changing the hw.acpi.disable_on_poweroff from default value of 1 to 0 fixes the problem. At least for now I don't get the panics on shutdown anymore.
Also, while running the kernel with WITNESS and INVARIANTS, I didn't get the panics (as I already said), and I get this in /var/log/messages:

Best regards.

Hello,
I have a Pentium 4 2.8E (with HT), and an Intel 865GBF motherboard.
After I made a bios upgrade I have this problem with it: every time I do a reboot or a shutdown the kernel hangs. Sometimes it gives a specific error message, sometimes the last lines of text are garbage, and rarely it just resets before it should.
Seems that it happens before the file system is unmounted, because every next boot I have problems with it. Until now I didn't lose any important file, but I assume that this can happen giving this situation.
Also, this does not happen if I compile a kernel without SMP support, or if I disable HT from bios (with SMP or not).
Running a kernel with INVARIANTS and WITNESS seems to fix this problem too.
I have attached a dmesg result after a boot -v.
Please let me know what other informations you need for solving this situation.
With respect,
