Re: Problem with ACPI and vmware

[Francis Yom <fyom-NeBS1MF9zuBBDgjK7y7TUQ@public.gmane.org>]

Hi Troy,

Pardon me on the idle patch.  When I looked at my processor.c file, I
realized I was looking at the wrong place and sure enough I did not
disable my 'pm_idle=acpi_pm_idle;' line as directed.  This fixed the
problem completely for me.  Now I just have to get the battstat program
to work ;)

FWIW, I have a Presario 2700 and I am running kernel 2.4.19 with xfs and
rmap14a.  I am running it with the 20021101 ACPI patch and it is working
fine.  I get battery, thermal zones, everything! :)  What made it work
was upgrading the BIOS to the latest F.12 revision which you can get
from compaq.  The F.12 bios has a fixed ACPI implementation and now my
laptop has working ACPI :)  

The only bug I have is that thermal zones are not always picked up at
boot.  I have to reboot (sometimes 2-3 times) and the thermal zones will
get discovered.  I am wondering what might be causing this.  Hmmmm...
Any ideas?

Many thanks!
Francis
