Absurdly high temperature reading - system shutdown

Michal Mazurek-2
After moving my old laptop around I got home, booted it and got a very
distressing message:

messages.2.gz:Jun 14 22:40:09 hopek /bsd: acpitz2: Critical temperature
4938C (52112K), shutting down

Perhaps some dust moved around, or a cable disconnected.
Unfortunately, the system shut down before it booted. I booted bsd.rd,
read some manpages and booted with -c 'disable acpitz' - everything
worked fine. I attach a diff to only shutdown if the temperature is
below 2000C. If it's above then it's too late to shut down anyway :)

BTW, for no apparent reason my laptop started working fine again.

Re: Absurdly high temperature reading - system shutdown

Marco Peereboom
The real issue is in acpiec.  Several attempts have been made at fixing
this but none has been working reliably enough :-(

It was pointed out to me to attach acpidump and dmesg. Kernel is custom
built to include bce.

I had noticed the following behaviour (maybe related or maybe not) in my
laptop:

- When the batt goes low the system shutdown with the same message.
The temp is always (not 100% sure) 110C. This is 100% reproducible
(every time batt goes low --> system shutdown).

I was trying to figure myself what is happening to introduce myself to
kernel code but if someone want to test something I'll glad to help.

This diff you are writing is a workaround.  It is not fixing the bug.

Somewhere higher, some acpi, aml, bios, or EC behaviour has provided
bad data, which has propogated up to the acpitz driver.

We will kind of needs these workarounds until the real bugs are found,
though, perhaps...

Shouldn't the sc_tmp, sc_crt and other variables be divided by 10 before
being displayed as Kelvins?
Even if the OS runs on Sun hardware. ;-)
