My server is failing to boot because of what I suspect is an error with the timeclock in ACPI, so I'd like to try to disable it in the course of troubleshooting it.
Per the handbook:
https://www.freebsd.org/cgi/man.cgi?query=acpi(4)&sektion=
I can disable 'timer', but from the boot prompt, I am unable to set
debug.acpi.disabled
for timer; I assumed I could set it with:
debug.acpi.disabled=timer
but it cannot seem to locate the option (with or without the timer) part, so perhaps I misunderstood the handbook, or am overlooking something glaring (which I think may be the case).
I was unable to boot into single user to adjust the loader.conf, as it fails with the same error.
What is the best way to go about setting this and disabling the timer so I can proceed with troubleshooting this further?
