ACPI never really worked on this machine, HOWEVER, turned out a BIOS
upgrade was required!  Its an IBM Xseries 345 with 2 Xeon CPU's
http://en.ecomstation.ru/hardware.php?action=item&id=1194

This is the update that was required:
http://www-304.ibm.com/jct01004c/systems/support/supportsite.wss/docdisp
lay?brandind=5000008&lndocid=MIGR-43902
(Maybe its usefull since the diskette images contains the BIOS images
etc).

ACPI 2.22 worked just fine on this machine. With the /SMP switch the
two Xeon 2.4 Ghz worked. No other switches where used. Turning on hyperthreading 
on resulted even in 4 CPU's in they eCenter. 

However one problem occured that is an error in ACPI. This error does
NOT occur when I install OS2APIC.PSD or have ACPI.PSD loaded and switch
off(!) hyperthreading support in the BIOS.

This problem was tested on eComStation 2.0 RC 1  ACPI 2.22, SMP kernel
104a.

The attached script from Steve Levine was used to tested the process
dump (note it has fixed paths in it Steve still needs to do some
cleaning up).

*Start 4os2

Then run pdump -i 4os2 

Choose F and S

Then choose to perform a dump. 

I can not produce a memory dump. What happens is that eComStation
freezes and the server then even automaticly reboots. The management CPU does this!
So something seems to going seriously wrong!!! The BIOS has
no entry about this reboot. So there is no trap screen.

Doing the same dump WITH OS2APIC.PSD installed from IBM installed and running the dump utility it all works fine.

So I have to conclude this is bug in ACPI.PSD. Don't know what else it
could be. Standard VGA driver installed and only /SMP in config.sys.

I also just tried to install ACPI.PSD 3.0 /3.01 but this results in another
problem. It traps at startup at the moment the PSD is loaded.
I just opened another ticket for that.

I ran the same test on an Intel Duo core with ACPI.PSD with the /SMP switch installed and this worked.

So a bit puzzled :-)
