(In reply to Lo=C3=AFc Bartoletti from comment #17)
Do you have crash dump available?

If no than we can try to boot with crashed /boot/loader.conf but with
"hw.usb.usbhid.enable=3D1" line commented out.

Than collect output of following commands

# kgdb /boot/kernel/kernel /dev/mem

(kgdb) info line *0xffffffff821134d8

Also, install sysutils/usbhid-dump and run usbhid-dump utility (it will det=
ach
all usb devices, so you need pipe output to file or replug usb kbd or ssh or
ps/2 keyboard)
