Subject: High latency on /sys/class/thermal

Hi all

Yesterday, I recompiled my kernel (git + tuxonice)
v2.6.30-rc1-1002-gac91f91, there were a couple of issues, the main one
is ilustrated bellow.

I am not familiar with the kernel code, but if you give me some
pointers, I will be glad to investigate this further

$time cat /sys/class/thermal/thermal_zone0/temp 
34000

real	0m6.613s
user	0m0.000s
sys	0m0.001s
