According to past and present kernel-parameters.txt, acpi=on
is _not_ a valid option.
...............................
acpi= [HW,ACPI] Advanced Configuration and Power Interface
Format: { force | off | ht | strict }
force -- enable ACPI if default was off
off -- disable ACPI if default was on
noirq -- do not use ACPI for IRQ routing
ht -- run only enough ACPI to enable Hyper Threading
strict -- Be less tolerant of platforms that are not
strictly ACPI specification compliant.
See also Documentation/pm.txt, pci=noacpi
acpi_sleep= [HW,ACPI] Sleep options
Format: { s3_bios, s3_mode }
See Documentation/power/video.txt
acpi_sci= [HW,ACPI] ACPI System Control Interrupt
trigger mode
Format: { level | edge | high | low }
acpi_irq_balance [HW,ACPI] ACPI will balance active
IRQs default in APIC mode
acpi_irq_nobalance [HW,ACPI] ACPI will not move
active IRQs (default)
default in PIC mode
acpi_irq_pci= [HW,ACPI] If irq_balance, Clear listed
IRQs for use by PCI
Format: <irq>,<irq>...
acpi_irq_isa= [HW,ACPI] If irq_balance, Mark listed IRQs
used by ISA
Format: <irq>,<irq>...
acpi_osi= [HW,ACPI] empty param disables _OSI
acpi_serialize [HW,ACPI] force serialization of AML
methods
acpi_skip_timer_override [HW,ACPI]
Recognize and ignore IRQ0/pin2 Interrupt
Override.
For broken nForce2 BIOS resulting in
XT-PIC timer.

This is the mesg about ML/twiki type opinions and advice I'm
tryin to make known. acpi=on doesn't exist or is purposely
neglected and undocumented. In either case it's almost certain
to be ignored by the kernel and have no effect, or possibly an
unintended one.
Be concerned about ACPI tho. It's becoming most important on
current systems where more than the original 15 IRQ's and IRQ
sharing is needed. IMO, if you need to add 'acpi=<any of the
options listed in kernel-parameters.txt>' to your kernel, what
you really need to add is better and standards compliant hardware
to your system. The facts are available before you purchase,
only opinions afterwards.
APIC isn't all that big a fsck'n deal. Nice to have, might
add a slight touch of performance to ACPI IRQ handling.
This thread is the last of me being an ogre about advice and
opinions as gleaned from ML's and twiki's when it's contrary to
past and current developer's and maintainer's documentation.
Probly why after years, I hardly post anymore.
