5.3 crash on boot

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:


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,

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.
