Yep. Let see. Don't remember. Ok, I'll just re-build with SMALL_KERNEL
and see what it was....
There are two ACPI ramdisk issues
1) acpi code references sensor_add and sensor_task_unregister which is
in kern_sensors.c. kern_sensors.c is !small_kernel
2) /sys/dev/acpi/dsdt.c defines DST which interferes with option DST
in the config file. I changed DST -> DST1 in /sys/dev/acpi/dsdt.c
That same file also references tsleep but does not include <sys/proc.h>
for the function prototype. Patch with both changes follows.
