Thanks Konrad.

I downloaded new code and still doesn't work(albeit different problem). I
will enumerate them below

(Please note 1, 2 and 3 are seen with old xen/next as well). What seemed
simple testing of pci passthrough via config changes doesn't seem to be the
case.

1. mkinitrd doesn't work in xcp ddk. I get below errors

mkinitrd -f ./initrd-2.6.32.ing 2.6.32
modinfo: could not find module ide-disk
No module ide-disk found for kernel 2.6.32, aborting.

I copied ide-disk.ko from
/lib/modules/2.6.27.42-0.1.1.xs0.1.1.737.1065xen/kernel/drivers/ide/ide-disk.ko(just
to check what other errors arise from mkinitrd in xcp ddk), I get

mkinitrd -f ./initrd-2.6.32.ing 2.6.32
modinfo: could not find module ide-disk
modinfo: could not find module dm-mem-cache
modinfo: could not find module dm-message
modinfo: could not find module dm-raid45

2. Looked into .config I have(generated via make menuconfig) and there isn't
anything on IDEDISK. I cross checked config file that comes with xcp source
code it has
...
CONFIG_BLK_DEV_IDEDISK=m
CONFIG_IDEDISK_MULTI_MODE=y
...

I copied above configs into my .config and when I run make(it asks some IDE
config related questions ) and these configs are deleted after that. I have
tried all options "y/n/m" to the questions and same result.

3. I downloaded .config file from
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.32.10-pvops-dom0-xen-stable-x86_32

there isn't IDEDISK config in it either and in addition "make tar-pkg"
doesn't work with this .config file. I get following errors

DEPMOD  2.6.32


/bin/sh: line 1:  3341 Killed                  /sbin/depmod -ae -F
System.map -b /root/kernel/linux-2.6.32/tar-install 2.6.32
make[3]: *** [_modinst_post] Error 137
make[2]: *** [sub-make] Error 2
make[1]: *** [tar-pkg] Error 2
make: *** [tar-pkg] Error 2

4. I tried with the vmlinuz and initrd image built from "2" above(I know
initrd image is not correct, I just wanted to try) and I get

[0.000000] ERROR: Unable to locate IOAPIC for GSI 2
[0.000000] ERROR: Unable to locate IOAPIC for GSI 9

Let me know how to proceed on this.

Thanks
