As a follow-up to this... adding the hint hint.acpi.0.disable="1" fixes
the suspend problems, but produces the following error messages on
boot-up:
unknown: <PNP0303> can't assign resources (port)
unknown: <PNP0f13> can't assign resources (irq)
unknown: <PNP0700> can't assign resources (port)
unknown: <PNP0501> can't assign resources (port)
unknown: <PNP0401> can't assign resources (port)
These only exist with the acpi hint above. Removing the hint and
reverting to a previous kernel (where ACPI is disabled because APM is
enabled) shows them with the hint in place too, but obviously acpi is not
enabled then. I have confirmed that this is new with the latest acpi
import.
The recent heads-up about hw.acpi.0.disable="1" has not fixed the problem
I am seeing.
Those ISA PNP IDs correspond to,
/usr/src/sys/isa/atkbdc_isa.c: { 0x0303d041, "Keyboard controller (i8042)" },/* PNP0303 */
/usr/src/sys/boot/common/pnpdata:ident=PNP0700 module=fd # PC standard floppy disk controller
/usr/src/sys/boot/common/pnpdata:ident=PNP0501 module=sio # 16550A-compatible COM port
/usr/src/sys/boot/common/pnpdata:ident=PNP0401 module=lpt # ECP printer port
/usr/src/sys/isa/psm.c: { 0x130fd041, "PS/2 mouse port" }, /* PNP0F13 */
These devices seem to work fine however.
