hint.acpi.0.disable="1", but that dont works... a don't know what
to
do... can someone help me?

Exactly where does it stop in the boot? Does the kernel load? Is this an
upgrade or a new install? A few more details will be needed to do more
than guess.

It seems to be a bug when using anything 5.x and above with any Toshiba laptops
and also some acer models.

I found this:

http://lists.freebsd.org/pipermail/freebsd-mobile/2004-March/003501.html

Unfortunately I haven't managed to find a 'reason' for the
occurrence, and im new to debugging freebsd and issues such as this, so
don't really know where to start the investigation myself.  If anyone else
can suggest a good start point, im happy to test any fixes/patches.

I'm guessing this is a new install (as you wouldn't have been able to
perform the installation yet, as it crashes on boot, unless its an updated 4.x),
try this:



When booting (be it from cd, or from hdd), stop the boot by pressing "any
other key" then at the prompt, type:

set hw.pci.enable_io_modes=0

Once typed, type "boot" (without the "'s obviously) and
attempt to continue your installation.  Once the system is installed happily,
add "hw.pci.enable_io_modes=0" (again, without "'s) to
/boot/loader.conf.

This should hopefully allow you to boot,

Hope this helps,
