XEN0 Kernel not booting on Athlon XP 64 X2 4400+

[KlinT <klint%klintcentral.net@localhost>]

Hi all,

Well I'm trying to setup Xen 2.0.7 on my new Athlon 64 X2 computer ... 
I'm running NetBSD 3.99.17 and everything runs ok ( maybe except for 
the SATA.II feature ) ...

So I install Xen as usual, according to the documentation ...

The problem is when I'm trying to boot the XEN0 kernel. I got a kernel 
error ( swapper error ) and then I enter the debugger ... :(
I've found that problem comes with USB/FireWire components, so I 
disable them in the bios and try to boot again the XEN0 kernel ...
Same problem but not at the same place :(

I've tried to build my own kernel from the source. I've successfully 
built the toolchain, and a XEN0 kernel using build.sh.
but trying to boot this kernel fails too ... Now, the system freeze ... 
but never at the same place.
Some times the boot process reach network configuration and then freeze 
... I was not able to boot entirely my system.

Any idea ??

I think that I have a similar problem than "Florent Parent" who post 
this thread "XEN0 kernel with options MULTIPROCESSOR".
And my kernel is not able to deal with the dual-core architecture of my 
cpu ...

I've also try to optimize the build using some options in /etc/mk.conf 
and the package pkgsrc/devel/cpuflags ... Don't know if it really works 
...

Many thanks,

Arnaud
