Instrumentation and lm_sensors

[Philip Prindeville]

I was wondering why FC3 doesn't try to run system-detect-sensors as
part of the standard install.  Most PC98 systems include motherboard
instrumentation for voltate, temperature, airflow, etc...

Also, when I run "service lm_sensors status", it gives me:

And I notice that while BIOS/Setup shows me the "system fan"
stats, for whatever reason lm_sensors isn't detecting it from
Linux.

Is there a fix for this?  Do I need to hand-tweak the configuration?

One other thing...  I noticed that if I don't change my /etc/grub.conf file
after doing an update to 2.6.11-1.35FC3, it hangs.  But changing
the args from "... quiet acpi=off" to "... quiet no-hlt" fixes that.

Doing a "reboot", the system hangs at  "Restarting machine".

Is this a known issue?

Dmesg show me:

ACPI: Power Button (FF) [PWRF]
ibm_acpi: ec object not found

before the shutdown.  Could this be related?  And does the BIOS
setting for ACPI standby need to be in S1 or S3?
