Re: [Xen-users] xen 3.0 testing ACPI problems / no PCI functionality
thats rubbish .. if you cant tell me what should be up with my config,
then better dont say anything at all. You even did not listen that I
compiled a vanilla kernel with the kernel config that does NOT work with
xen, but with the vanilal kernel PCI works goddamn fine.
Secondly, if you read my posts before more carefully then you'd know
that my bios supports ACPI and that the xen kernel (although without
PCI) boots but then it's rebooting and saying that I didnt not allocated
enough memory for the memory reservation of dom0 (while without apci
enabled it doesnt do this and boots fine, just without PCI).
Thus its neither a fault of my config nor of anything else that is
related to my person, but only to xen and its faultiness.

FFS .. I do not care about ACPI .. now I ask you the _second
time_ to refer to my PCI problem as without PCI nothing works at all.
If you use one of our kernels PCI will likely work fine. If you've got a
broken bios that doesn't do acpi then disable it with acpi=off on the
xen command line. I'd much rather help you get something working with a
known good kernel than trying to second guess all the possible ways you
could have botched your own config...

First of all .. as I said ACPI was the reason why my mashine was
constantly rebooting as - if ACPI enabled - xen does did not detect
the amount of RAM properly and thus is always claiming it wasnt
enough.
Sencondly, the xen kernel config is not that much different
to mine ..
my kernel is just more lightweight tho.
...
ACPI isnt the main problem, could you please also refer to
the second
problem, which is of much more importance to me?
Can you not just put 'acpi=off' on the *xen* command line (not the
linux one)?
Please try this with the -xen kernel.

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).
Any reason not to be using our -xen kernel config? It has
ACPI and sems
to work fine for the almost everyone.
Ian
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
