This sysctl must be set while in single-user mode, or from /etc/sysctl.conf. The crash(8) man page has additional guidance.
X is not installed on that machine, running only console and console frooze,
could do nothing with the keyboard, will try the ddb thing if I don't get progress
with the ACPI thing BSDfan666 pointed out.

boot> boot -c
UKC> disable apm
UKC> quit

If this works, use config(8) to save the changes permanently.
Will try this and get back when done.
