Hi
I'm experiencing this problem on my dell laptop: on first boot temperatures are
correctly detected, fan starts correctly when temperature goes up. If I suspend
(to ram) the laptop and then resume, I get zero values by all three thermal
zones (0 °C), and fan never starts, I have to reboot to fix this.
I'm using kernel 2.6.32-rc8 from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32-rc8/ , which AFAIK is
kernel vanilla compiled for ubuntu.
I also tried to build kernel with zen patchset (version 2.6.32-rc7) and the
issue is present as well.

Best Regards
Federico Chiacchiaretta
