Hello.
My machine (hp compaq 6510b) has some strange problem related with
acpi/thermalzone/ac.
When I power it on with ac plugged-in, all seems to work fine.
But when I unplug ac following things happens:
1. About every 10 second below message shows up:
acpitz2: TZ5_: failed to read _TMP
acpitz2: TZ5_: failed to read temp
2. CPU temperature start to rise slowly, even if CPU is 100% idle.
3. When temperature gets to about 50 degC, fan speed up and acpitz
message stops showing up.
4. When fan cools down CPU to 45 degC, acpitz message again
shows up on console, CPU temperature start to rise,
fan cools cpu, etc...
5. If I plug in ac, it doesn't help.
6. If reboot it in that state then there's a difference in acpitz
kernel message while booting (dmsg included), but above "loop" still
ocurs.
7. Only powering off and on with ac connected solve the problem.
dmesg (ac connected, powering on)

I've also notice that hw.sensors.acpitz* values are changing while cpu
