[Bug 212782] [bhyve] Increasing VM_MAXCPU to >= 26 will result in ACPI MADT table corruption

I've tested a solution today and it seems working. 1. Start apcupsd with --term-on-powerfail apcupsd_enable="YES" apcupsd_flags="--term-on-powerfail" 2. Put the following line into /etc/rc.shutdown.local test -f /var/run/powerfail && /usr/local/sbin/apcupsd --killpower Now, when the UPS power is exhausted, apcupsd starts the shutdown procedure and exits. The system shuts down without any haste, as it pleases, and at the very end "apcupsd --killpower" is called and poweroffs the UPS. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ signature.asc Description: PGP signature
