P4 HT with SMP kernel, FreeBSD 5.2.1-p4 problem

[Claudiu Dragalina-Paraipan]

Hello,

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:

Apr  3 17:28:59 oxygen kernel: lock order reversal

This appear once, shortly after a startup.

Best regards.
