Then add +1 to what Michael Biebl already asked: why that message should be showed?Because the watchdog feature was enabled at compile-time and you presumably want it to work. If you add 'nowatchdog' to the kernel parameters then the kernel will not attempt to set up the watchdog, and the error message will not appear.
Thanks, i didn't know that parameter, but i don't want to disable the lockup detector.
I'm sure that kernel devels will find a better way to handle unsupported hardware and the situation where the watchdog cannot be used (anyone without a local APIC will see this message?). From the user point of view, i think that the best is to handle silently the unsupported case (at least in quiet boot) and to show a meaningful message in the syslog. From the current message, if you are not a kernel developer, it's not clear if it's a warning or an error message. In other words, it's not clear if the watchdog will function or not.
