>From comment #40:
* Fans not working (at least on F.04).
* Thermal zone/sensors not working.
* ACPI parsing aborts in several places due to initialization bugs (Linux
does work around this)
* CPU Powersaving (aka C-State switching) only works if you boot the
machine without AC adapter attached.
* No critical shutdown temperature returned for anything else but Windows.
I got this message with F.03:
Dec 11 17:20:47 dre kernel: [ 1.830747] ACPI Exception: AE_OK, No or invalid
critical threshold 20090521 thermal-384
I've upgraded to F.06, and now get this:
Dec 12 00:56:08 dre kernel: [ 1.843983] thermal LNXTHERM:01: registered as
thermal_zone0
Dec 12 00:56:08 dre kernel: [ 1.843990] ACPI: Thermal Zone [TZ01] (61 C)
Regarding these messages:
Dec 12 12:14:55 dre kernel: [ 1.439863] ACPI Error (psargs-0359):

I looked in all the SSDTs and did not see the _PPC method defined
anywhere, so wondering where the theory in comment #43 about loading all
the SSDTs comes from. I also didn't find _REG in any of the SSDTs.
Both CPUT and PSSC are defined in DSDT, so I'm not sure why we can't
parse those. I'll dig into that.
I consider the current outstanding list of issues to now be:
* Fans not working (at least on F.04).
* ACPI parsing aborts in several places due to initialization bugs (Linux
does work around this)
* CPU Powersaving (aka C-State switching) only works if you boot the
machine without AC adapter attached.
Curious about the statement regarding fans though. Are you simply
stating that because /proc/acpi/fans/ is empty? Or are your fans not
actually spinning up? My machine is running warm, but I definitely hear
and feel fan output.
Thanks.
