Completely disabling ACPI rarely works with modern machines.
Please try to run the following DTrace script (dtrace -s script-file) and
capture its output.
#pragma D option flowindent
fbt::acpi_intr_handler:entry
{
self->trace = 1;
}
fbt:::entry
/self->trace/
{
printf("arg0 = %#x, arg1 = %#x, arg2 = %#x", arg0, arg1, arg2);
}
fbt:::return
/self->trace/
{
printf("@%p ret = %u", arg0, arg1);
}
fbt::acpi_intr_handler:return
{
self->trace = 0;
exit(0);
}
