Hi,

I build new kernel using svn revision 308866, now it changed to

aw_thermal0: <Allwinner Thermal Sensor Controller> mem 0x1c25000-0x1c253ff irq 29 on simplebus0
aw_thermal0: #0: alarm 90C hyst 15C shut 105C

so I will try to put some load on it. This should lead to higher
temperatures, currently I have 67 degrees. I am interested in longer
lasting load...

Thanks for notice.

Regards,
Milan
