Re: Fatal trap 12 during bootup on Dell Cpt with acpi enabled

It says the ACPI driver cannot be loaded after boot in the cases of booting single user and booting multiuser. It always panics after detecting ata0.

Could you please start up without acpi loaded, and then try loading acpi
later with kldload and see if that panics, too?
If so, try and get a dump by writing 'call dumpsys' at the ddb>  prompt. Once
you have the dump, when you reboot again (without acpi loaded, so it doesn't
panic), the dump will be written to /var/crash.

If you can then upload that dump somewhere, someone might be able to figure
out what the problem is.
