Is there any real downside in turning off ACPI?  Especially for a server
that will be running 24x7?

Tom

I have been ignoring these for a couple of months and have not been struck
down by lightning from above.

There have been reports of a couple of devices not working that sounded to
me like potential IOAPIC/IRQ/etc mapping problems caused by using bad data
from ACPI tables (whether the BIOS had a bogus table or FreeBSD a bogus
parser is unknown to me).  This is rare.

In short, if it seems to work, it probably does.
If it doesn't work, try turning off ACPI in the BIOS.
