Hi all,

hopefully my question isn't too dump and you don't hit me to hard for it:

I've checked out the 'linux-2.6-merge.hg' tree. Everything fine so far except 
two things:

1) Why is devpts disabled for domUs? The ssh daemon will not work without. Or 
do i have missed something? How do i have to setup the domU to get the sshd 
(openssh-4.2p1) working. With the xen-3.0.0 release, it works fine.

2) When compiling the kernel the compile fails with error message:

  make mrproper
  make menuconfig
  make
  ...
  arch/i386/kernel/built-in.o: In function `i8237A_resume':
  i8237.c:(.text+0x7751): undefined reference to `smp_processor_id'
  i8237.c:(.text+0x77b1): undefined reference to `smp_processor_id'
  make: *** [.tmp_vmlinux1] Fehler 1

This occures if SMP is set off cause the machine does have only one CPU. 
Adding "#include <linux/smp.h>" to "arch/i386/kernel/i8237.c" makes it 
compilable. Is that a correct fix?  Btw. i'm using a gcc-4.0.2.

Thank you for giving me some hints

Thomas
