xen 3.0 testing ACPI problems / no PCI functionality

[Patrick <patrick_@freenet.de>]

Hello,

I just encountered that the xen 3.0 testing (from the mercurial 
repository) will not work if I have ACPI compiled into the kernel. 
Although the kernel will build properly, I cant boot it, as xen is 
constantly moaning about the amount of memory reservated for dom0 and 
thus is rebooting again and again (the appropiate settings are given and 
correct).

I confirmed this by NOT compiling ACPI into my kernel at all .. then xen 
boots up fine... BUT then I do not have PCI functionality at all (which 
means lspci is empty and all my PCI devices do not work, even not if I 
try to load the appropiate driver manually). Again the settings (config) 
are compiled in and correctly set (which simply means I wasnt a jerk and 
forgot compiling PCI support in tho).
I am using sis5513 as mainboard chipset and another confirmation on my 
side, as far as the problerm above's concerned, is that I tried exactly 
the same kernel config (without the xen config symbols of course) and 
compiled a vanilla 2.6.12.6 kernel manually .. it boots up fine and PCI 
support is also given, while doing the same with a xen-patched kernel 
will not work at all and results in pci non-functionality.

Any further confirmation about the two problems I mentioned above would 
be appreciated.


best regards,
Patrick
