Thanks for your reply.The message "acpi_tz0: _CRT value is absurd, ignored 
(256.0C)" was printed on my screen when I install FREEBSD9.0.And the message 
appears from time to time when I used my laptop.Annoying~~~~

Until now,I do not notice any problem casused by the message obviously. I read 
the source code of the acpi_thermal.c,but have no idea about what temperature 
the acpi_tz0 detected.The message tell me _CRT value is absurd,how to make it 
reasonable and not appears from time to time on my screen?Thanks for your 

ps:I install freebsd9.0 to other machine,this message does not appears.

A solution to what problem? The "ignored" message isn't a problem on its 
own; do you think it causing some other trouble that you didn't describe?
