In cases where ACPI doesn't work, on some machines, the acpi information is
faulty and openbsd has to work around it (like on some Intel branded
motherboards.) On other machines, the acpi tables are valid but expose
bugs in the openbsd parser. The first step towards resolution would be
to run 'acpidump' and submit it to OpenBSD via sendbug along with dmesg
and this back trace.

It is an old observation that the best writers sometimes disregard the rules of
rhetoric. When they do, however, the reader will usually find in the sentence
some compensating merit, attained at the cost of the violation. Unless he is
certain of doing as well, he will probably do best to follow the rules.
