Hi, 
 
I try to use XEN, but have some problems with getting it started on my 
machine. (My settings are listed at the bottom). 
 
My first problem is that if I boot into Xen the kernel hangs while 
booting, such that I have to do a hard reset. It doesn't hang always at 
the same place, but most often around the time when suse wants to start 
the suse firewall. However XEN boots when I turn DMA of. (ide=nodma). 
This is very annoying since I need DMA, so what can I do? 
 
I read somewhere that this could be caused by the generic IDE driver and 
one should compile only the specific IDE (PIIx...) driver into the 
kernel. 
 
I tried this but run into the following problem. I use the standard 
configuration file from Suse for Xen as placed 
in /boot/config-2.6.11.4-21.8-xen and changed some options (mainly only 
the IDE driver modules.) 
(make ARCH=xen menuconfig; make ARCH=xen all) 
However after compiling for a long time I see the following output. 
 
[...] 
 AR arch/i386/lib/lib.a 
 GEN .version 
 CHK include/linux/compile.h 
 UPD include/linux/compile.h 
 CC init/version.o 
 LD init/built-in.o 
 LD .tmp_vmlinux1 
arch/xen/kernel/built-in.o(.text+0x85b): In function `ctrl_if_suspend': 
arch/xen/kernel/ctrl_if.c:466: undefined reference to `teardown_irq' 
drivers/built-in.o(.text+0x45cf7): In function `balloon_process': 
drivers/xen/balloon/balloon.c:275: undefined reference to 
`kmap_flush_unused' 
make: *** [.tmp_vmlinux1] Error 1 
 
What is causing the problem? How do I get arround this? 
Any specific options I must set (or must not set) in menuconfig to get 
the kernel compiled? 
 
Further, if I want to use the latest xen sources (like xen 2.0.7 or even 
unstable, how do I combine this with the provided (already patched) SUSE 
kernel sources? 
 
My settings: 
Compaq Armada M700 Laptop 
Suse 9.3 with Xen (latest Update as of today). 
gcc version 3.3.5 20050117 (prerelease) (SUSE Linux) 
Xen 2.0.5c 
(source) of kernel:/usr/src/linux-2.6.11.4-21.8 
(running) Kernel: vmlinuz-2.6.11.4-21.8-xen 
 
Help is very much appreciated, since I am totally stuck after several 
nights of trying out.
