Works (?), but is ugly and clumsy. * I can use CPUID, but I guess then I should be prepared to catch SIGILL on old CPUs so I don't gain much from the above. * I could look in dmesg, but this is really ugly since this is a ring-buffer, and the particular boot-up message is not guaranteed to be in the buffer at all. * There _should_ be some sysctl for this. Can someone please do this? Or point me to how I'd go about doing it myself? -- Frode Vatvedt Fjeld To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
